Why Training with CrossFit Will Supercharge Your Next HYROX Race
(And Why Top Athletes Like Tia-Clair Toomey Are Taking Notice)
If you're preparing for your next HYROX race and want to improve your performance, integrating CrossFit into your training might be your game-changer. At Mobilus, we’ve seen how functional fitness, community-driven coaching, and high-intensity training can give HYROX athletes the competitive edge they need.
And the proof? Athletes like Tia-Clair Toomey, eight time CrossFit Games Champion, entered the HYROX scene and made headlines with a world-record-breaking time of 54mins and 24secs with Joanna Wietrzyk in the 2025 Houston HYROX Women’s Pro Doubles—cementing the powerful synergy between CrossFit and HYROX.

What is HYROX?
HYROX is a high-intensity fitness race format consisting of 8 x 1 km runs, each followed by a functional workout station like sled pushes, wall balls, rowing, burpee broad jumps, and more. Designed to test strength, stamina, speed, and mental grit, it’s often referred to as the “marathon of functional fitness.”

Why CrossFit is the Perfect Training Base for HYROX
1. Functional Movements That Translate Directly
HYROX workouts mirror the movements found in most CrossFit boxes:
Sled pushes/pulls = Prowlers and weighted pushes
Wall balls = CrossFit staple
Burpee broad jumps = Regular in conditioning WODs
Rowing/SkiErg = Common warm-ups and workouts
Farmers carries & lunges = Often found in partner WODs
At Mobilus Singapore, we train these regularly so you can confidently tackle each HYROX station.
2. Endurance and Engine Building
HYROX rewards those with an unshakable aerobic engine. CrossFit workouts build this by combining:
High-intensity intervals
Long-duration WODs
Mixed-modality conditioning
Every Minute On the Minute (EMOM) and As Many Reps As Possible (AMRAP) formats
This is how athletes like Toomey, and many Mobilus athletes maintain high performance across 8km of running and 8 high-power workout zones.
3. Strength That’s Functional and Fast
HYROX isn’t about being the biggest—it's about being efficient, explosive, and adaptable. CrossFit athletes develop:
Powerful posterior chains (great for sleds and lunges)
Strong cores (essential for carries and transitions)
Mobility and movement economy (for injury prevention and speed)
Mobilus programs strength cycles that focus on real-world movement, not just barbell PRs.
4. Mental Fortitude
Each CrossFit WOD is a battle of willpower—just like a HYROX race. You’re constantly tested to:
Push through pain
Stay calm under fatigue
Stick to pacing plans
Make fast, focused decisions
Tia has often credited her CrossFit experience for building mental discipline, which clearly translated to her HYROX debut.
