The Physiology behind fitness races of the future
Over the past few years, fitness races have emerged as one of the most exciting and accessible trends in the world of functional training. Designed to test both aerobic endurance and functional strength, these events offer a unique blend of challenge and community that continues to captivate athletes across the globe.
Unlike traditional sports competitions or gym-based challenges, fitness races provide a standardized, race-style format that brings structure, clarity, and repeatability to the world of high-intensity fitness. They strip things down to the essentials: move fast, stay consistent, and outlast the clock. No advanced gymnastics. No heavy Olympic lifts. Just raw work capacity, grit, and well-rounded athleticism.
Why Fitness Races Are So Popular
1. Accessible Yet Demanding
One of the biggest draws of fitness races is that they’re scalable and inclusive. You don’t need elite skills to participate—just a baseline of fitness, determination, and a willingness to push yourself. But make no mistake: these races are no walk in the park. The combination of sustained effort and functional movement creates a test that is both approachable and brutal, depending on your pacing, prep, and mental game.
2. The Thrill of Measurable Performance
With standardized formats across locations and events, fitness races allow athletes to track their performance over time or compare results globally. This consistency creates a competitive edge that’s often missing in more “randomized” workout environments. Whether you're racing against the clock, your previous time, or another athlete, there's always a clear benchmark to chase.
3. A New Kind of Challenge
Fitness races appeal to those who want something more grounded than obstacle course races and more endurance-focused than short metcons. It’s a middle ground where runners learn to lift, and lifters learn to run. It's a space for hybrid athletes—those who value resilience, capacity, and the ability to push hard for 60+ minutes with minimal rest.
4. Community Without Ego
One of the best parts of these events is the energy in the room. Unlike some fitness competitions that can feel intimidating or skill-gated, fitness races bring out a wide range of people—everyday athletes, weekend warriors, and competitive pros alike. Everyone’s working through the same movements, the same layout, the same suffering—and that shared experience fosters a real sense of camaraderie.
5. Functional, Practical Fitness
The movements tested in fitness races are generally practical, full-body actions—pushing, pulling, carrying, lunging, throwing, jumping. They simulate the kind of real-world strength and endurance you might need in daily life or sport. For many athletes, it feels relevant and rewarding, not just flashy or technical.
Fitness Races vs. CrossFit: What's the Difference?
While CrossFit is built around constantly varied functional movement, fitness races follow a fixed-format event. That means every competitor completes the same distance, movement volume, and order of tasks—making it easier to test and track performance over time.
Fitness races are typically:
Less skill-intensive (no high-skill gymnastics or heavy Olympic lifts)
More grind-based, relying on muscular stamina and aerobic endurance
Longer in duration, demanding sustained output over 60–90 minutes
Rather than testing who can do the most complex movements, fitness races test who can maintain performance while managing fatigue.
The Physiological Demands of Fitness Races
Aerobic Capacity
Definition: Your body’s ability to deliver and use oxygen during sustained activity.
Why it matters: With a total of 8 km running, plus functional movements in between, aerobic capacity is the cornerstone of success.
Example: An athlete with a strong engine can run a steady 5:00/km pace and still complete movements like 100 wall balls without gassing out.
Muscular Endurance
Definition: The ability of a muscle group to sustain repeated contractions.
Why it matters: Every station taxes a different group—legs, grip, core—and you're expected to recover between efforts while continuing to move.
Example: During 100m sandbag walking lunges, your quads and glutes stay under load for several minutes. If your endurance is low, pace and form drop quickly.
Anaerobic Threshold / Lactate Tolerance
Definition: The point at which your body accumulates lactic acid faster than it can clear it.
Why it matters: The event rewards athletes who can flirt with the redline without crossing it. Go too hard early? You’ll crash.
Example: Going too fast on the sled push in round 2 might leave you toast by round 4 because you exceeded your threshold too soon.
Functional Strength & Core Stability
Definition: Practical strength and trunk control for real-life and sport movement patterns.
Why it matters: Movements like the sled pull, farmers carry, and wall balls demand powerful but controlled effort under fatigue.
Example: A weak core means collapsing posture, slower sled pushes, and more missed wall ball reps late in the race.
Mental Grit & Pacing Discipline
Definition: The ability to endure discomfort and stay mentally engaged during high effort.
Why it matters: Fitness races are about strategy, not sprints. Athletes must manage intensity wisely across a long duration.
Example: Choosing to break 100 wall balls into 5 sets of 20 instead of going for 50 and burning out is what separates the experienced from the wrecked.
Adding Fitness Race Training to CrossFit
The good news? You don’t need to overhaul your entire training plan to prepare for a fitness race.
Just 1–2 dedicated workouts per week can build:
Aerobic base
Muscular stamina
Pacing awareness
Mental resilience
CrossFit already builds general physical preparedness (GPP) across strength and intensity. But fitness race workouts fill the gaps by emphasizing:
Long-duration output
Repetitive movement efficiency
Transition speed
Fatigue management
And because most race-style movements are low-skill but high-output (sleds, carries, ergs), they can be added to your week without requiring recovery like heavy lifting or high-skill gymnastics.
Think of fitness race sessions as your engine-building zone. They’ll make you more consistent, more durable, and more composed in long workouts—and that absolutely carries over into CrossFit WODs and competitions.

Final Thoughts
Fitness races are a powerful test of both body and mind. They're not about technical gymnastics or 1RMs. They're about grit, pacing, repeatability, and resilience.
For CrossFit athletes or anyone looking to elevate their engine, adding fitness race-style training once or twice a week is a game-changer. You’ll boost endurance, learn to manage fatigue, and become a more adaptable, balanced athlete overall.
It’s time to train for the long haul—and come out stronger on the other side.
