Frequently Asked Questions

Do I need to be an experienced runner to start this add-on?

No. The program adapts to your current running level. Whether you run a 5:30/km pace or a 3:45/km pace, ChAIron adjusts the intervals, pacing ranges, and progression to match your abilities.

How many days a week should I run to train for HYROX?

Most athletes see the best progress with 2–3 targeted run sessions per week, depending on their main program volume. ChAIron automatically balances intensity and recovery.

What if I already run regularly outside of HYROX training?

You can still use this add-on. ChAIron merges your current running routine with HYROX-specific adaptations, meaning you’ll run with better mechanics and improved race-day pacing.

Will this help me maintain pace after tough stations like sleds and burpees?

Yes. The add-on specifically builds “fatigue-resistant running.” You’ll train run–station transitions so your legs stay stable and your breathing stays controlled even after high-effort stations.

Does this improve all eight 1km legs or just the first few?

All eight. The add-on includes pacing strategy and targeted sessions for early-race, mid-race, and late-race 1km splits, especially the “slow bleed” legs (4, 5, 6).
