HYROX Doubles is a different race to singles — and most teams make the same mistakes. After speaking to dozens of doubles pairs and analysing race data, here are the 10 things every team should know before their first doubles race.
1. Don't Split Everything 50/50
The biggest mistake new doubles teams make is splitting every station equally. If one partner is significantly stronger at sled push and the other is faster at rowing, lean into those strengths. An uneven split where each person does more of their strong stations will always beat a "fair" 50/50 approach. Use our Station Allocator to find the optimal split based on your individual times.
2. Practice Changeovers — Seriously
Changeovers (the moments where you swap between partners at a station) can cost 30–60 seconds per station if they're sloppy. That's up to 8 minutes lost in a race. Practise the handover: where do you stand? How do you signal? Who adjusts the equipment? These details matter.
3. You Both Run Every Run — And Stay Together
Both partners must complete every 1km run segment — you can't split the running. You also need to stay within 15 seconds of each other. Your team is only as fast as the slower runner. This means running compatibility with your partner matters more than station strength. If there's a big fitness gap, the faster runner gets held back on every single run, and that adds up enormously over 8km.
4. Communication Is a Skill
Decide in advance how you'll communicate during the race. A simple system: the resting partner counts reps or calls out distance for the working partner. Keep instructions to 2-3 words maximum — "Ten more" or "Last set" — because your partner can't process complex instructions under fatigue.
5. Decide Your Split Before Race Day
Don't show up and improvise. Have a written plan for exactly who does what at every station, including the order of alternation. Print it. Tape it to your wrist. Race-day adrenaline makes it easy to forget even simple plans.
6. The Stronger Partner Should Not Go First on Everything
It's tempting to have your stronger partner always go first to "break the station open." But this means they get less rest between their own work periods. Alternate who goes first at each station to balance recovery.
7. Farmers Carry and Lunges Are Where Doubles Gets Tactical
At stations 6 (farmers carry, 200m) and 7 (sandbag lunges, 100m), the splitting strategy matters enormously. A 100/100m split on farmers carry means two pickups and putdowns each. A 200m/0m split means one partner walks the full distance — harder but faster overall. Test both approaches in training.
8. Wall Balls Break Partnerships
Station 8 (wall balls) is where fatigue is highest and coordination matters most. Agree in advance: how many reps each? Who goes first? What's the break strategy? A common approach is 25-25-25-25 (alternating sets of 25), but some teams prefer front-loading the fresher partner.
9. Know the Penalty Rules — 3 Minutes Per Infraction
Every form violation, missed rep, or rule infraction costs 3 minutes in time penalties. That's enormous — it can turn a good race into a disaster. Incomplete burpee reps, separating from your partner at a station transition, missing a lap — all 3-minute penalties. Make sure you both know the rules cold before race day. Stay within 15 seconds of each other on runs and complete every rep properly, even if it means going slower.
10. Celebrate — You Just Did Something Most People Never Will
Doubles is harder than it looks because the psychological pressure of not wanting to let your partner down adds a layer that singles doesn't have. Whatever your time, crossing that finish line together is an achievement. Take the photo, analyse the result later, and start planning the next one.
