Why Hyrox Doubles is Exploding
Hyrox Doubles has become one of the sport's fastest-growing divisions. The format is simple: two athletes share the workload across all 8 stations, alternating reps or splitting stations by strength. Only one athlete works at a time. The other rests, cheers, and recovers.
The result is a race that's harder than it looks and more strategic than most athletes expect. Done right, a well-matched Doubles pair will run faster and hit stations harder than either athlete would individually. Done wrong, a mismatched pair drags each other to a painful, slow finish.
Here's how to get it right.
Choosing the Right Partner
Partner selection is the most important decision in Hyrox Doubles. Athletes make the mistake of signing up with their best friend without checking if their fitness profiles match.
Ideal partnership traits:
- Similar running pace — you share runs in Doubles, so wildly different paces create chaos at transition
- Complementary strengths — a strong upper-body athlete (SkiErg, Burpees) paired with a strong lower-body athlete (Sled, Lunges) creates natural station splits
- Compatible communication styles — you'll be 2 feet from each other for 60+ minutes. If one partner is a screamer and one isn't, expect friction
- Similar competitive goals — if one partner wants to win and one wants to finish, that's a problem by station 5
The fitness gap rule: If one athlete would finish Solo in 65 minutes and the other in 85 minutes, the stronger partner carries the weaker one. This works in practice, but it's demoralizing and usually leads to conflict. Aim for partners within 10-15 minutes of each other on estimated Solo finish times.
Understanding the Doubles Format
In official Hyrox Doubles rules:
- Both athletes run each 1km segment together
- At stations, athletes can split reps any way they choose — alternating 1:1, blocks of 10, or splitting the station entirely (one partner does all reps, other does none)
- Station reps are doubled compared to Solo (wall balls: 200 reps vs 100, lunges: 200m vs 100m)
- One athlete works at a time; the other must stay in the designated rest zone
The doubled station reps make station management critical. A pair that splits reps evenly will each do roughly what a Solo athlete does — but with rest periods built in. Smart pairs use those rest periods to recover for subsequent runs.
Station Splitting Strategy
How you divide station reps is where most strategy lives. Three main approaches:
1. Alternating Blocks (Most Common)
Athlete A does 10 reps, Athlete B does 10 reps, repeat. Simple, equal, easy to track. Good for stations where both athletes are similarly capable (Wall Balls, Rowing).
2. Strength-Based Splits
Assign stations based on individual strengths:
- Upper-body dominant partner takes: SkiErg, Burpee Broad Jumps, more Rowing
- Lower-body dominant partner takes: Sled Push, Sled Pull, Lunges, Farmers Carry
- Even split for Wall Balls (pure conditioning)
This approach is fastest but requires knowing each athlete's profile well. Test it in training before race day.
3. Fatigue-Based Adjustments
The flexible approach: plan alternating blocks but allow the stronger-feeling partner to take extra reps mid-race. Requires communication and trust. Works well for pairs with solid race experience.
Regardless of approach, agree on the strategy before race day. Don't negotiate at station 5 when both of you are exhausted.
Training Together
Most Doubles pairs make the mistake of training individually and just showing up together on race day. That's how you get poor transitions, conflicting pacing decisions, and misread energy levels.
Joint Training Protocol (6-8 Weeks Pre-Race)
Once per week: Full station run-through together. Do all 8 stations using your planned splitting strategy. This is where you find the problems — wrong pace, confusing transitions, disagreements about rest periods — before race day.
Once per week: Shared running sessions. If your running paces differ, work on running together at a shared pace. The slower runner sets the pace; the faster runner holds back. Practice the 1km run → station transition hand-off.
Individual training otherwise. Outside of shared sessions, train individually. You each have different weaknesses to address. Over-training together leads to social friction and inefficiency.
Communication Drills
Practice these specific hand-off moments:
- Run to station transition: Who goes first? Decide before you arrive at the station — not at the station line.
- Rep counting: The resting partner counts reps. The working partner focuses on effort. Practice this explicitly — miscounted reps add penalty time.
- Energy check-ins: Every 2-3 stations, briefly check in on how each partner feels. Adjust splits if someone is fading.
Race Day Logistics
Gear Coordination
Both athletes need to arrive ready to go. Avoid gear hand-offs mid-race (passing gloves, adjusting straps) — it costs time and creates confusion. Each partner should have:
- Their own gloves (if using them for Sled Pull or Farmers Carry)
- Their own hydration (water belt or plan to drink at stations)
- Matching bib placement so officials can track you
Warm-Up
Warm up together. 10-15 minutes of shared jogging and light movement primes both athletes for the first run. Agree on your first station split during warm-up. Get on the same page before the horn goes.
First Run Pacing
The biggest Doubles pacing mistake: the stronger partner sets a pace the weaker partner can't hold. Agree on a first-run pace that both athletes can execute comfortably. If the stronger partner wants to go faster, they can lead during the last 200m. The priority is arriving at SkiErg with both athletes ready to work.
Common Doubles Mistakes
- Unequal rest abuse: The resting partner standing too far from the station, wasting 10 seconds on every transition. Stay close. Be ready.
- Undercommunicating fatigue: One partner suffering in silence while the other thinks everything is fine. Speak up early.
- Wrong station splits: Giving the Sled Push to the lighter, less powerful partner because "it's their turn." Play to strengths, especially on the hardest stations.
- Not knowing the rep counts: The doubled station reps catch many pairs off guard mid-race. 200 wall balls is not 100. Know the numbers cold.
- Racing against each other: It sounds absurd, but ego sometimes turns partners into competitors at key stations. You're one team. Every rep either partner does is a team rep.
Doubles vs. Solo: Is One Harder?
Doubles is different, not necessarily harder or easier. The rest periods between reps allow for harder individual efforts per rep — but the total volume and strategic complexity increases. Most athletes report that Doubles feels more demanding mentally and less demanding physically than Solo.
If you've done a Solo Hyrox and want a new challenge, Doubles is a natural progression. It rewards teamwork, strategy, and communication in ways the Solo format can't.
Key Takeaways
- ✓ Choose a partner with similar run pace and compatible strengths
- ✓ Decide your station-splitting strategy before race day, not during
- ✓ Train together at least once per week for 6-8 weeks pre-race
- ✓ Practice rep-counting and transition hand-offs explicitly in training
- ✓ Know the Doubles rep counts — they're double Solo, not the same
- ✓ Communicate energy levels throughout the race and adjust splits accordingly
Doubles done right is one of the most fun formats in competitive fitness. Find a partner who pushes you, build a strategy, and execute it together.
