Your First HYROX: 7 Mistakes That Cost Beginners the Most Time

Short answer: most first-timers don't run out of fitness, they make avoidable mistakes. The biggest are starting too fast, not practising running on tired legs and getting no-repped on lunges and wall balls.

Here are the seven to avoid. This guide is written by Kalern Thomas, founder of Kalective Fitness, who has coached for more than 10 years and raced the 2026 HYROX World Championships in Stockholm (mixed doubles 25–29, 57:52).

1. Running the first kilometre too fast

Everyone does it, because the start is exciting and everyone around you is doing it. Run the first kilometre at the pace you expect to hold late in the race. You'll pass a lot of the people who went off hard.

2. Only training the stations

The stations are the interesting part, so people spend their training on sleds and wall balls. But half of the race is running. If you can only fix one thing, build your easy running.

3. Never running on tired legs

Running fresh and running straight after a sled push are different skills. At least once a week, do a session that combines running with station work so the feeling isn't a surprise on race day.

4. Going all-out on the sleds

Pushing to failure leaves you standing still, and standing still is the slowest thing you can do. Use short, fast steps with low hips, and take planned pauses at the turns.

5. Not knowing the movement standards

Judges will no-rep lunges where the knee doesn't touch the floor and wall balls that miss the target or don't hit squat depth. A no-rep costs you the effort and the time. Read the current HYROX rulebook and train to the standard from day one.

6. Wasting time in the Roxzone

The area between the running track and the stations is on the clock. Jog through it and know which way you're going. If you can, watch an earlier wave to see the layout before you race.

7. Trying something new on race day

New shoes, a new breakfast or a new gel are all risks you don't need. Wear what you trained in and eat what you've eaten before hard sessions.

What to do instead

• Pick a realistic pace and test it in training before the race.

• Decide your wall ball sets in advance and stick to them from the first rep.

• Write a short race plan and read it in the start pen.
