From Runner to Hybrid Athlete: Your Guide to Hyrox and Marathon

Written by Will Duru, BSc (Hons) Sport and Exercise Science, award-winning Personal Trainer with over 10 years of experience in strength training  and optimising recovery .

As personal trainer with over a decade of experience, a sports science degree, and a passion for helping clients achieve their absolute best, I, Will Duru, have seen countless transformations. I’ve guided athletes through the grueling preparations for marathons, half-marathons, CrossFit competitions, and the intense demands of Hyrox events. My approach is rooted in science and honed by years in the trenches, earning me the reputation of an award-winning strength and conditioning coach. But among all the incredible journeys I’ve been privileged to witness, Lucy’s stands out as a testament to what’s possible when you embrace a truly holistic approach to fitness.

When Lucy first walked into my gym, she was, by her own admission, a runner. A dedicated one, no doubt, with a good aerobic base, but her strength training was, shall we say, sporadic at best. She’d dabble in a few exercises here and there, but it wasn’t a core component of her regimen. Her focus was almost exclusively on logging miles, a common narrative I encounter with many endurance athletes. While running is fantastic for cardiovascular health and mental fortitude, it often leaves significant gaps in overall physical development, particularly in terms of strength, power, and resilience.

My vision for Lucy was clear, and it was ambitious: to transform her into a true hybrid athlete. This wasn’t about abandoning her love for running; it was about elevating her entire physical capacity, making her stronger, more powerful, and less prone to injury, ultimately enhancing her performance across multiple disciplines. This article will take you through Lucy’s incredible journey, detailing the strategic shifts in her training, the remarkable gains she made, and the profound impact it had on her body, mind, and competitive spirit. You’ll learn what it truly means to be a hybrid athlete, the critical role of strength, how nutrition adapts, and how recovery becomes paramount. And for those inspired by Lucy’s story, I’ll also touch upon how the 12reps app can be your guide to building your own hybrid athlete training program.

Understanding the Hybrid Athlete

Before we dive deeper into Lucy’s transformation, it’s crucial to understand what we mean by a ‘hybrid athlete.’ In the fitness world, this term has gained significant traction, and for good reason. A hybrid athlete is someone who excels across multiple, often disparate, physical domains. They possess a unique blend of strength, endurance, power, and agility, allowing them to perform exceptionally well in diverse challenges, from long-distance running to heavy lifting, and everything in between. They are not specialists in one area but rather generalists who have mastered the art of being incredibly fit in a multifaceted way.

 What does a hybrid athlete have to possess? It’s more than just being able to run far and lift heavy. It requires a profound understanding and development of all major energy systems within the body. Our bodies produce energy through three primary systems, each dominant during different types of activity:

 The ATP-PC (Adenosine Triphosphate-Phosphocreatine) System: This is your immediate energy system, providing quick bursts of power for activities lasting up to about 10-15 seconds. Think of a maximal lift, a short sprint, or a powerful jump. It’s anaerobic, meaning it doesn’t require oxygen, and relies on readily available ATP and phosphocreatine stores in the muscles. Training this system is crucial for explosive movements and raw power.

 The Anaerobic (Glycolytic) System: This system kicks in for activities lasting from roughly 15 seconds to two minutes, like a hard 400-meter sprint, a set of high-rep squats, or the intense bursts found in Hyrox. It breaks down carbohydrates (glycogen) without oxygen, producing lactic acid as a byproduct. Training this system improves your ability to sustain high-intensity efforts and tolerate the burning sensation associated with lactate accumulation. This is where we often talk about the ‘lactic system’ and how to overcome and train it – it’s about improving your body’s efficiency at buffering and clearing lactate, allowing you to push harder for longer.
 

The Aerobic (Oxidative) System: This is your long-duration energy system, fueled by oxygen and capable of sustaining activity for minutes, hours, or even days. It uses carbohydrates and fats to produce ATP efficiently. Marathon running, long cycling sessions, or sustained efforts in a Hyrox race primarily rely on this system. Developing a robust aerobic base is fundamental for recovery between high-intensity efforts and for overall endurance.

A hybrid athlete must train all these systems synergistically. It’s not about maximising one at the expense of another, but rather optimising each to support overall performance. This comprehensive approach is why hybrid training is often considered superior for overall fitness and why it leads to a more well-rounded, resilient, and capable physique. It’s about building a body that’s ready for anything, a body that can adapt and excel in any physical challenge thrown its way. This is the essence of athletic strength training and the athlete strength training program we implemented for Lucy.

The Foundation Phase: Building Strength and Resilience

When Lucy and I first discussed her goals, it became immediately clear that while her running endurance was commendable, her underlying strength and joint resilience needed significant attention. This wasn’t a criticism; it was an observation common among many endurance athletes who often overlook the foundational importance of strength training. For Lucy to truly become a hybrid athlete, capable of excelling in diverse fitness competitions like Hyrox and still smashing marathon times, we had to build a robust foundation. This meant prioritising strength above all else for the initial phase of her training.
 
Our first six months together were dedicated almost exclusively to this foundational strength-building. This wasn’t about simply lifting heavy weights; it was about intelligent, progressive overload designed to challenge her nervous system and build genuine, functional strength. We focused heavily on compound movements – exercises that work multiple muscle groups and joints simultaneously. Think squats, deadlifts, overhead presses, and rows. 
 
These movements are incredibly efficient for building overall strength, improving coordination, and stimulating significant muscle growth, which is crucial for muscle building and overall athletic development. We started with manageable weights, emphasising perfect form, and gradually increased the load as her technique solidified and her strength improved.
 
Beyond traditional strength exercises, we integrated plyometrics. These are explosive movements like jumps, bounds, and hops, designed to improve power and speed. Plyometrics teach the body to produce maximum force in minimal time, which is vital for activities requiring quick bursts of energy, like those found in Hyrox or even a strong finish in a marathon. They also enhance the nervous system’s ability to recruit muscle fibers efficiently, making her more responsive and agile.
 
Furthermore, we incorporated a variety of functional exercises. These movements mimic real-life activities and train the body in multiple planes of motion, preparing it for the unpredictable demands of fitness competitions and trail running. The goal was to challenge her nervous system to continuously adapt, ensuring her body was not just strong in isolated movements but resilient and adaptable in dynamic, complex scenarios. This constant adaptation is key to long-term progress and injury prevention.
 
Crucially, this foundational phase also heavily emphasised joint health and resilience. Years of high-volume running can put significant stress on joints. By strengthening the muscles surrounding her knees, hips, and ankles and improving her overall stability, we were actively working to bulletproof her body against potential injuries. This proactive approach is paramount for any athlete looking for longevity in their sport.
 
When we began, Lucy’s strength baselines, while not non-existent, certainly had room for growth. Her deadlift was around 40kg, her squats were at 40kg, and pull-ups were a struggle, managing only 2 in a go. The sled push, a staple in Hyrox training, was limited to about 45kg. These numbers weren’t a reflection of her effort but rather the consequence of a training history that hadn’t prioritised this type of strength development. Our mission was clear: to systematically elevate these numbers, setting the stage for her incredible transformation into a true hybrid athlete. This initial focus on athletic strength training was the bedrock upon which all future success would be built.

Lucy's Strength Gains

The dedication Lucy showed during our foundational strength phase was truly inspiring. She embraced the challenge, understood the ‘why’ behind every exercise, and consistently pushed her limits. The results were, frankly, astounding. Her body adapted, her nervous system became more efficient, and her strength numbers soared, laying a concrete foundation for her journey as a hybrid athlete. Let’s talk numbers, because they tell a powerful story of progression and the effectiveness of a well-structured athlete weightlifting program:

 Deadlift Progression: 40kg to 120kg. This was perhaps the most dramatic and impactful change. The deadlift is a full-body exercise, a true test of raw strength and power in the posterior chain. Starting at a respectable 40kg, Lucy meticulously worked on her form, built her grip strength, and developed incredible core stability. Throughout just over a year, she was confidently pulling 120kg – three times her starting weight! This wasn’t just about moving weight; it was about unlocking immense power that translated directly into her running economy, her ability to navigate obstacles in Hyrox, and her overall resilience. This kind of deadlift training is transformative.

Pull-up Improvement: 2 to 12 Consecutive Reps. When we began, Lucy could manage two pull-ups with significant effort. Pull-ups are a fantastic indicator of relative strength and upper body pulling power. Through a combination of assisted pull-ups, negative reps, and targeted back and bicep work, she systematically built the strength required. To go from 2 to 12 unassisted pull-ups in a single set is a monumental achievement, showcasing incredible upper body strength endurance and a testament to her consistent effort in muscle building.

Squat Development: 40kg to 70kg. The squat is the king of lower body exercises, crucial for powerful running, jumping, and overall athletic performance. Lucy’s initial 40kg squat was solid, but we focused on deepening her squat, improving her hip mobility, and strengthening her glutes and quads. Her progression to 70kg demonstrated significant gains in lower body strength, stability, and power, directly benefiting her running stride and her ability to handle the leg-intensive movements in fitness competitions.

Sled Push Power: 45kg to 150kg. The sled push is a brutal yet highly effective exercise for developing explosive leg power and anaerobic capacity, making it a cornerstone of Hyrox training. Starting at 45kg, Lucy quickly adapted to the demands of this movement. We progressively loaded the sled, pushing her limits and building her ability to generate sustained power. Her ability to push 150kg was a clear indicator of her newfound strength and endurance, a direct result of dedicated athletic strength training.

These gains weren’t accidental. They were the result of a carefully periodised athlete strength training program that emphasised progressive overload, proper recovery, and meticulous attention to form. We utilised a variety of training methods, including heavy lifting, accessory work, and specific drills to address any weaknesses. This phase truly cemented her physical capabilities, transforming her from a runner who occasionally lifted into a formidable, strong athlete ready for the next stage of her hybrid journey.

Integrating Anaerobic and Power Training

With Lucy’s strength foundation firmly established, it was time to strategically reintroduce and integrate more specific anaerobic endurance training and power development into her regimen. This phase was about building on the strength we had cultivated, translating that raw power into dynamic, sport-specific performance, and preparing her for the multifaceted demands of fitness competitions like Hyrox. This wasn’t a return to her old running-only ways; it was a sophisticated blend, where strength training remained a critical component, but with different training methods and objectives.
 
The reintroduction of endurance work was gradual and intelligent. Instead of simply adding more long-distance runs, we focused on structured intervals, tempo runs, and circuit training that mimicked the demands of Hyrox and other hybrid events. This allowed us to build her anaerobic capacity, her ability to sustain high-intensity efforts, without compromising her newly acquired strength. We incorporated short, intense bursts of activity followed by controlled recovery periods, pushing her lactate threshold and improving her body’s efficiency at clearing metabolic byproducts.
 
Power training became a key focus. While plyometrics in the foundational phase built a base for explosiveness, this stage refined it. We used exercises like kettlebell swings, box jumps, medicine ball throws, and Olympic lifting variations (like power cleans and snatches, scaled appropriately) to develop her ability to generate force quickly. This is distinct from pure strength; power is the application of strength with speed. For a hybrid athlete, power is essential for everything from bursting out of a sled push to maintaining pace during a sprint segment in a Hyrox race, or even a strong kick at the end of a marathon.
 
The strength training itself evolved. While compound movements remained central, the rep ranges, sets, and rest periods were adjusted to align with the new goals. We moved towards more strength endurance work, where she would perform more repetitions with moderate weight, challenging her muscles to work under fatigue. This was crucial for the sustained efforts required in events like Hyrox, where you might be performing burpee broad jumps or wall balls for extended periods. We also incorporated supersets and complexes to increase the metabolic demand of her lifting sessions, blurring the lines between traditional strength training and conditioning.
 
Our periodisation approach became more complex, cycling through phases of higher intensity, higher volume, and dedicated recovery. This ensured she was peaking for specific events while continuously developing all aspects of her fitness. This integrated approach to her hybrid athlete training program allowed Lucy to seamlessly transition between heavy lifting and high-intensity cardio, making her a truly formidable competitor. It was a testament to how marathon and athletic strength training could be combined to create a truly comprehensive weightlifting program, preparing her for any challenge.

Energy Systems Training for Hybrid Athletes

For a hybrid athlete like Lucy, understanding and specifically training all three energy systems – aerobic, anaerobic, and ATP-PC – is not just beneficial; it’s essential. My sports science background has taught me that true athletic versatility comes from optimising how your body produces and utilises energy under different demands. This phase of Lucy’s training was about fine-tuning these systems to ensure she had the metabolic flexibility to excel in any scenario.
 
Aerobic Base Development: Even with the shift towards strength and power, maintaining a strong aerobic base remained paramount. This system is the engine for sustained efforts, but it’s also crucial for recovery between high-intensity intervals and strength sets. We continued with steady-state cardio, but also incorporated longer, lower-intensity sessions to build her endurance capacity. A well-developed aerobic system means faster recovery, allowing her to perform more work in subsequent sessions and adapt more effectively to the training load. This is the foundation for any marathon strength training program.
 
Anaerobic Capacity Building: This is where we pushed Lucy’s limits in the middle ground – efforts lasting from 30 seconds to a couple of minutes. Think of the intense bursts in a Hyrox race, like the burpee broad jumps or the sled pull. We used high-intensity interval training (HIIT) with work-to-rest ratios designed to maximise her time in the anaerobic zone. This type of training improves the body’s ability to produce energy without oxygen and, crucially, enhances its capacity to buffer and clear lactic acid. The goal was to increase her tolerance for discomfort and her ability to sustain powerful output even when her muscles were screaming.
 
ATP-PC System Training: While we built a base for this in the foundational strength phase with heavy lifts and plyometrics, we continued to refine it. This system is about pure, unadulterated power – the ability to generate maximal force in a very short period. We incorporated short, maximal effort sprints, heavy single or double repetitions in lifting, and explosive jumps. This ensures that Lucy always had that immediate burst of power available, whether it was for a heavy deadlift, a quick transition in a fitness competition, or a powerful surge during a trail run.
 
Lactic Acid Tolerance and Clearance: This is often referred to as training the ‘lactic system’ and is a critical component for Hyrox hybrid athletes. When the anaerobic system is heavily engaged, lactic acid and other metabolic byproducts accumulate, leading to the burning sensation and fatigue. We trained Lucy not only to tolerate this discomfort but also to improve her body’s efficiency in clearing these byproducts. This involved specific workouts that pushed her into the lactate zone, followed by active recovery periods. Over time, her body became more adept at utilising lactate as fuel and clearing it from the muscles, allowing her to maintain a higher intensity for longer and recover faster between efforts.
 
By systematically targeting each energy system, we ensured Lucy was not just strong, or just fast, or just enduring, but a true blend of all three. This comprehensive approach to energy system training is what truly defines a hybrid athlete and allows them to perform at an elite level across a wide spectrum of physical challenges.

Weekly Training Structure

One of the most common questions I get about hybrid athlete training programs is, “What does a hybrid athlete’s weekly sessions look like?” It’s a valid question, as balancing strength, endurance, and power can seem daunting. For Lucy, her weekly schedule was meticulously planned to ensure adequate stimulus for all systems while allowing for crucial recovery. It wasn’t about doing everything every day, but instead strategically placing different types of training to maximise adaptation and minimise overtraining. A typical week for Lucy, once she was fully into her hybrid training, might look something like this:
 
Monday: Strength Focus (Lower Body & Power). This session typically involves heavy compound lower-body movements, such as squats or deadlifts, followed by plyometrics or power exercises (e.g., box jumps, broad jumps). The emphasis here was on lifting heavy and moving explosively. This session directly contributed to her deadlift training and overall athletic strength training.
 
Tuesday: Anaerobic Endurance & Conditioning. This day would be dedicated to high-intensity interval training (HIIT) or Hyrox-specific conditioning. This could involve sled pushes, burpee broad jumps, wall balls, or rowing intervals. The goal was to push her anaerobic capacity and lactate tolerance, preparing her for the demands of fitness competitions. This was crucial for her Hyrox training.
 
Wednesday: Active Recovery / Aerobic Base. A lighter day, focusing on active recovery like a gentle run, cycling, or swimming. The intensity would be low, aimed at promoting blood flow and aiding recovery without adding significant stress. This also helped maintain her aerobic base, which is essential for marathon training.
 
Thursday: Strength Focus (Upper Body & Full Body). This session would target upper body strength with exercises like overhead presses, rows, and pull-ups (where she excelled!). We’d also include some full-body functional movements or accessory work to address any imbalances and continue her muscle building efforts.
 
Friday: Hybrid Session / Skill Work. This day often combined elements of strength and endurance in a circuit format, or focused on specific skills required for upcoming events. For example, practicing transitions for Hyrox, or working on running form drills. This session often felt like a mini-fitness competition in itself.
 
Saturday: Long Endurance / Trail Run. This was her dedicated longer endurance day, often a run, sometimes incorporating varied terrain or inclines, especially when preparing for trail runs in Spain. This maintained her cardiovascular fitness and mental endurance.
 
Sunday: Complete Rest. Crucial for physical and mental recovery. This day was about recharging and allowing her body to adapt to the training stress.
 
This structure allowed for systematic progression in all areas. The key was the intelligent sequencing of sessions, ensuring that high-stress workouts were followed by adequate recovery or lower-intensity work. It’s a dynamic plan, always adjusted based on her recovery, performance, and upcoming events, but it provides a clear picture of how a comprehensive hybrid athlete training program is implemented.

Body Composition and Physique Changes

One of the most visually striking and functionally beneficial outcomes of Lucy embracing the hybrid athlete lifestyle was the significant positive change in her body composition. Many people associate strength training with ‘bulking up’ and endurance training with becoming ‘skinny.’ However, the beauty of a well-executed hybrid athlete training program is that it allows you to build a leaner physique, combining the best of both worlds.
 
When Lucy was primarily a runner, her body composition reflected that of a typical endurance athlete, lean, but perhaps lacking in significant muscle mass, especially in the upper body and posterior chain. As we integrated more heavy-weightlifting and muscle-building into her routine, her body began to transform. She developed more lean muscle mass, particularly in her legs, glutes, back, and shoulders. This wasn’t about becoming bulky; it was about becoming more dense, more powerful, and more defined.
 
The increased muscle mass had several key benefits. Firstly, muscle is a metabolically active tissue, meaning it burns more calories at rest than fat. This contributed to a reduction in body fat percentage, even without drastic dietary restrictions, leading to a leaner, more athletic appearance. Secondly, the development of functional strength and muscle improved her posture, stability, and overall movement efficiency, which translated into better running form and reduced risk of injury.
 
Lucy’s physique became a testament to the power of hybrid training: strong, athletic, and aesthetically balanced. She wasn’t just a runner anymore; she looked like an athlete capable of anything. This transformation underscored the fact that for many, hybrid training is the optimal path for achieving a truly fit and capable body, moving beyond the limitations of single-sport specialisation. It’s about optimising for performance, and the aesthetic benefits of a leaner, more muscular physique are a fantastic byproduct.

Nutrition for the Hybrid Athlete

Training like a hybrid athlete demands a sophisticated approach to nutrition. You’re asking your body to perform high-intensity strength work, sustained endurance efforts, and explosive power movements, often within the same week. This level of physical output requires precise fueling and recovery. For Lucy, changing her nutrition to compliment her new training program was as critical as the training itself. It wasn’t about restrictive dieting or chasing weight loss through deprivation; it was about strategic intake to support performance, recovery, and body composition goals. Here’s how her nutrition evolved:
 
Protein: The Building Block of Muscle. With the significant increase in strength training and muscle building, Lucy’s protein requirements naturally increased. Protein is essential for muscle repair and growth, and for supporting the immune system, which can be stressed by intense training. We focused on consuming high-quality protein sources at every meal, aiming for roughly 1.6-2.2 grams of protein per kilogram of body weight daily. This included lean meats, poultry, fish, eggs, dairy, and plant-based options like legumes and tofu. Timing also became important, with a focus on protein intake post-workout to kickstart recovery.
 
Carbohydrates: The Fuel for Performance. For a hybrid athlete, carbohydrates are not the enemy; they are the primary fuel source for high-intensity efforts and endurance. We shifted from a general intake to a more periodized approach. On heavy training days, particularly those involving long runs or intense Hyrox-style conditioning, her carbohydrate intake would be higher to ensure adequate glycogen stores. On lighter days or rest days, her carb intake would be slightly reduced. We emphasised complex carbohydrates like whole grains, fruits, and vegetables for sustained energy, while also utilising faster-digesting carbs around workouts for immediate fuel and recovery. This strategic fueling was vital for her marathon strength training and overall performance.
 
Fats: Essential for Health and Hormones. Healthy fats play a crucial role in hormone production, nutrient absorption, and overall health, all of which are vital for an athlete’s performance and recovery. We ensured a consistent intake of healthy fats from sources like avocados, nuts, seeds, olive oil, and fatty fish. While not a primary energy source during high-intensity exercise, fats provide a dense energy source for longer, lower-intensity efforts and contribute significantly to satiety and overall well-being.
 
Beyond macronutrients, hydration was paramount. Lucy learned to consistently monitor her fluid intake, especially around training sessions and during competitions. Electrolyte balance also became a focus, particularly during longer endurance efforts or in hot conditions. This comprehensive nutritional strategy ensured Lucy was always adequately fueled for her demanding training schedule, optimising her energy levels, recovery, and ultimately, her performance as a Hyrox hybrid athlete.

Recovery and Rest Protocols

In the relentless pursuit of becoming a hybrid athlete, it’s easy to fall into the trap of thinking more is always better. However, as an experienced coach, I know that training is only half the equation; the other, equally critical half, is recovery and rest. For Lucy, as her training volume and intensity increased, so too did the importance of her recovery protocols. Without adequate rest, the body cannot adapt to the training stimulus, leading to stagnation, burnout, and increased risk of injury. This is a non-negotiable component of any effective athlete strength training program. Here’s what recovery and rest meant for Lucy:
 
Sleep: The Ultimate Performance Enhancer. This is the cornerstone of recovery. During sleep, our bodies repair muscle tissue, consolidate memories, and regulate hormones crucial for performance and well-being. We emphasised consistent sleep schedules, aiming for 7-9 hours of quality sleep per night. This meant creating a conducive sleep environment and prioritising rest, even when her schedule felt packed. Lack of sleep can negate the benefits of even the most perfectly designed training program.
 
Active Recovery Methods: On her designated active recovery days (like Wednesday in her typical week), Lucy engaged in low-intensity activities such as light cycling, swimming, or gentle walks. These activities help to increase blood flow, reduce muscle soreness, and promote nutrient delivery to tired muscles without adding significant stress. It’s about facilitating recovery, not hindering it.
 
Stress Management: Training is a physical stressor, but life also brings its own stresses. We discussed strategies for managing overall stress levels, as chronic stress can impair recovery and performance. This included mindfulness practices, spending time in nature, and ensuring she had adequate downtime away from training and work.
 
Periodised Rest Days: Just as training is periodised, so too should rest. Lucy had dedicated complete rest days built into her weekly schedule (typically Sunday). Beyond that, we incorporated deload weeks every few months, where training volume and intensity were significantly reduced. This allowed her body to fully recover, supercompensate, and come back stronger for the next training block. These planned breaks are vital for preventing overtraining and ensuring long-term progress in any hybrid athlete training program.
 
By diligently adhering to these recovery and rest protocols, Lucy ensured that her body was always ready to meet the demands of her rigorous training. It allowed her to push her limits consistently, make remarkable gains, and ultimately, perform at her peak in every fitness competition she entered. Recovery isn’t just about what you don’t do; it’s an active process that’s just as important as the training itself.

Lucy's Competition Success

The ultimate validation of Lucy’s transformation into a hybrid athlete came through her remarkable performance in various fitness competitions. Her journey wasn’t just about personal bests in the gym; it was about translating that newfound strength, endurance, and power into real-world competitive success. Her achievements are a testament to the effectiveness of a well-structured hybrid athlete training program and her unwavering dedication. Lucy’s competitive resume became incredibly diverse and impressive:
 
15 Hyrox Competitions: This is where her hybrid prowess truly shone. Hyrox, a fitness race that combines 1km of running with one functional workout station, repeated eight times, is the ultimate test of hybrid athleticism. Her strength gains, particularly in deadlift training and sled push power, combined with her enhanced anaerobic capacity, allowed her to dominate these events. She consistently improved her times, showcasing her ability to seamlessly transition between strength and endurance demands.
 
2 Marathons Under 3:15: Despite the heavy focus on strength, Lucy didn’t just maintain her running ability; she significantly improved it. Her two marathons, both completed under the impressive time of 3 hours and 15 minutes, are a direct result of her marathon strength training. The increased leg strength, improved running economy, and enhanced resilience from her weightlifting program meant she could sustain a faster pace for longer, with less fatigue and a reduced risk of injury.
 
Trail Runs in Spain: Her hybrid training also opened up new avenues for adventure. The strength and conditioning she developed proved invaluable for the varied terrain and unpredictable demands of trail running. Her ability to handle ascents, descents, and technical sections with power and agility made her a formidable presence on the trails, especially during her challenging trail runs in Spain.
 
Turf Games Participation: These team-based fitness competitions require a broad range of physical abilities, from heavy lifting to gymnastics and endurance challenges. Lucy’s well-rounded athletic development, a direct outcome of her comprehensive athlete strength training program, allowed her to contribute significantly to her team’s success, showcasing her versatility and competitive spirit.
 
Lucy’s journey from a dedicated runner to a multi-faceted hybrid athlete, capable of excelling in such diverse and demanding events, is a powerful narrative. It demonstrates that with the right guidance, a strategic training plan, and unwavering commitment, the human body is capable of incredible adaptations and achievements. Her success is a beacon for anyone looking to transcend the limitations of single-sport specialisation and unlock their full athletic potential.
