Ke Wynn One training tool I take seriously is the race simulation.
As a masters athlete who has raced HYROX Men’s Open, Men’s Pro, and Mixed Doubles, I’ve learned that a sim should not be treated as another workout to smash.
Simulation places a huge load on the body, nervous system, and mind. Unless you’re an elite athlete with exceptional recovery capacity, it is not a workload most of us can tolerate frequently. Do them too often, or too hard, and you increase the risk of overtraining, injury, and arriving at race day already fatigued.
The goal of a sim is not to prove how fit you are.
The goal is to learn.
A good HYROX simulation helps you understand:
✅ How well you can hold your pace
✅ Which stations cost you the most time
✅ Where your running starts to fall apart
✅ How your body responds under race-like fatigue
✅ What finish time may be realistic
✅ How you and your partner communicate and transition in doubles
I typically use two kinds of simulations: half sims and full sims.
Half sims are my diagnostic tool. They are less demanding, take less time, and allow me to repeat them more regularly. I use them 1–3 months before race day to uncover weaknesses, sharpen stations, practise transitions, and make adjustments early.
Full sims are closer to a race-day rehearsal. I usually schedule one 2–3 weeks before the event to estimate a realistic finishing time and prepare mentally for the demands ahead.
But I don’t go all out.
I keep the full sim at around 70–80% of my race effort. I want enough intensity to get useful feedback, without sacrificing recovery or risking injury close to the race. A hard sim one week before an event may seem productive, but it can easily compromise race-day readiness.
For athletes chasing a faster finish or a PB, simulations deserve a place in the training calendar.
Schedule them weeks or months in advance by calculating backwards from your race day, recover from them properly, and use the results to train smarter.
A simulation is not a workout or a race.
It is preparation for your best race.
