1. Doubles is not a 50/50 split
The most common mistake in HYROX Doubles is starting with "let's just split everything evenly." That sounds fair, but it ignores the things that actually decide the outcome: different strengths, different recovery speeds, and different costs in the run immediately after a station.
The real objective is not equal work. It is the fastest stable team outcome. If one athlete can take a larger share of a station without destroying the next run, that is often better than a symmetrical split. Design your race around total team time, not individual fairness.
2. Doubles weight and rule specs
One of the most important things to understand about Doubles is that the weights are Pro-equivalent. If you go in thinking "two people means lighter," you will be in for a rough surprise.
| Station | Open (reference) | Doubles Men | Doubles Women |
|---|---|---|---|
| SkiErg | 1,000 m | 1,000 m | 1,000 m |
| Sled Push | 152 kg | 202 kg | 152 kg |
| Sled Pull | 103 kg | 153 kg | 103 kg |
| Burpee Broad Jump | 80 m | 80 m | 80 m |
| Row | 1,000 m | 1,000 m | 1,000 m |
| Farmers Carry | 2 x 24 kg | 2 x 32 kg | 2 x 24 kg |
| Sandbag Lunges | 20 kg | 30 kg | 20 kg |
| Wall Balls | 6 kg / 3 m | 9 kg / 3 m | 6 kg / 3 m |
Core Doubles rules
- Runs are together: both athletes run side by side. You cannot send one partner ahead; you must match the slower pace.
- Workout stations allow free swaps: either partner can do any share of the reps. One partner doing the entire station is also allowed.
- No simultaneous work: only one athlete can work the station at a time (e.g., you cannot both throw Wall Balls at the same time).
- Unlimited swaps: there is no cap on how many times you switch, but each swap adds a few seconds of transition time.
3. Rules that shape your strategy
In HYROX Doubles, the pair progresses through the race together. That means pacing gaps, unclear hand-offs, and station confusion all turn into time loss very quickly.
Three rules with the biggest strategic impact
| Rule | Strategic impact | What to decide in advance |
|---|---|---|
| Runs are together | The slower partner sets the pace ceiling | Agree on a maximum run pace beforehand |
| Free workout swaps | You can skew work toward the stronger athlete | Ownership ratios and swap points per station |
| Unlimited swap count | More swaps mean more rest but more transition loss | Optimal number of swaps (too many costs time) |
In short, Doubles is not a race where one strong athlete drags the team. Pairs who stay organized and share a clear procedure beat pairs who are fitter but disorganized. Doubles rewards clarity more than improvisation.
4. Station-by-station split patterns
The best way to split stations depends on the nature of each workout. Here is how to think about all eight stations.
Endurance stations (SkiErg / Row)
On the erg stations, the general principle is "the more efficient athlete takes a larger share." A common split is 600-700 m for the stronger partner and 300-400 m for the other.
- Set the swap point by distance (e.g., "swap at 500 m"), not by feel
- Having the stronger partner start usually produces a steadier opening pace
- Row taxes the back and legs heavily, so factor in how each partner recovers before the next run
Power stations (Sled Push / Sled Pull / Farmers Carry)
Sled stations use Pro-equivalent weights, so skewing work toward the heavier or stronger partner is very effective. However, having one person push the full 50 m of Sled Push destroys breathing completely, so a 25 m + 25 m swap is the standard approach.
- Sled Push: one partner pushes 25 m then swaps. If there is a large body-weight gap, shift to 30 m / 20 m
- Sled Pull: grip fatigue is the main limiter. Give the front half to the partner with stronger grip
- Farmers Carry: 200 m total, usually 100 m + 100 m. If one partner's grip can last, doing the full 200 m solo is an option
Repetition stations (Burpee Broad Jump / Sandbag Lunges / Wall Balls)
Repetition-based stations have high rep counts, making swap design the most important factor.
| Station | Even split | Skewed split | Swap tip |
|---|---|---|---|
| Burpee Broad Jump (80 m) | 40 m / 40 m | 50 m / 30 m | Pick the swap point using a floor marker |
| Sandbag Lunges (100 m) | 50 m / 50 m | 60 m / 40 m | Practice a smooth sandbag hand-off |
| Wall Balls (100 reps) | 50 / 50 | 40-30-30 (3 swaps) | Count reps out loud and call the swap |
- 50-50: simple, but the second set of 50 is brutally fatiguing and often leads to a slowdown
- 40-30-30: the stronger partner opens with 40 reps. Three swaps distribute fatigue well
- 30-20-30-20: very fine-grained swapping. Best fatigue distribution but highest transition loss
- Recommended: 40-30-30: the best balance between transition cost and fatigue management
5. Strategy by pair type
The right strategy depends on the kind of pair you are. Identify which type you are closest to and use it as a starting point.
Type A: Runner + Strength athlete
This is the most naturally balanced pairing.
- The runner holds back on runs to match the strength athlete's pace
- Sled stations and carries: strength athlete takes 60-70%
- SkiErg and Row: runner takes 60-70%
- Wall Balls and Burpee Broad Jump: roughly even, or slightly skewed toward the strength athlete
Type B: Evenly matched pair
Both athletes have similar fitness levels.
- Default to an even split across most stations
- The two stations where small differences show up most are Sled Push and Wall Balls. Skew only those toward the slightly stronger partner
- On runs, do not chase a fast pace. Synchronize rhythm rather than speed
- Standardize every swap pattern so there is zero hesitation. That alone is the biggest time saver
Type C: Experienced athlete + First-timer
This pair has the largest fitness gap. Planning matters more here than in any other combination.
- The experienced athlete takes the majority of sled work (first-timers often cannot handle Pro-level sled weight)
- The first-timer takes more Row and SkiErg, where pacing matters more than raw strength
- Drop the run pace from the start: if the first-timer blows up in the second half, the whole team stalls
- Check the first-timer's Wall Balls limit beforehand and design the split around that ceiling
6. Run pacing and communication
Many Doubles teams lose time not on the station itself but in the run leading into it and in the talk around the swap. If one athlete surges and the other chases, the pair pays for it later.
Run pacing principles
- Runs 1-3: enter at the slower partner's comfortable pace. Do not try to bank time here
- Runs 4-6: workout fatigue is accumulating. Accept a pace drop and check in with each other verbally
- Runs 7-8: assess remaining workouts and decide whether to save legs or push. This is the only section where race-day adjustment is acceptable
Preset phrases that work on race day
You do not need long conversations during the race. Agree on these short phrases in advance and they will eliminate hesitation on the floor.
| Situation | Phrase example | Meaning |
|---|---|---|
| Arriving at a station | "You first" / "I'll start" | Confirm who opens the station |
| Swapping | "Switch" / "Go" | Swap cue (one word, always the same) |
| Pace check | "Pace is good" / "Slow it down" | Run pace adjustment |
| Reps remaining | "20 left" / "Last 10" | Countdown on Wall Balls, etc. |
| Emergency | "Stop" / "30-second break" | Signal to avoid pushing through a breakdown |
In team racing, smooth minutes are worth more than flashy minutes. Design your communication around that principle and it will hold up when fatigue sets in.
7. Pacing by target time
Doubles target times differ from solo Open times. Use the table below as a reference for setting realistic goals with your partner.
| Target time | Per run | Avg. workout | Avg. Roxzone | Pair level required |
|---|---|---|---|---|
| Sub-70 | 4:15 - 4:30 | 3:00 - 3:30 | 0:45 - 1:00 | Both athletes solo sub-85 or better |
| Sub-80 | 4:45 - 5:00 | 3:30 - 4:00 | 1:00 - 1:15 | Both athletes solo sub-95 or better |
| Sub-90 | 5:15 - 5:30 | 4:00 - 4:30 | 1:15 - 1:30 | Both athletes solo sub-105 or better |
| Finish goal | 5:45 - 6:30 | 4:30 - 6:00 | 1:30 - 2:30 | Can run 5 km + gym experience |
8. Common mistakes and how to avoid them
Doubles-specific failures are different from solo mistakes. Knowing them in advance is often enough to avoid them.
| Mistake | Why it happens | How to avoid it |
|---|---|---|
| Both partners blow up on Sled Push | Underestimated Pro-level weight | Practice at 202 kg (Men) at least once before race day |
| Run pace falls apart after Run 5 | Fatigue gap becomes visible in the back half | Enter Runs 1-4 deliberately slow. Do not bank time |
| Every swap costs 10-15 seconds | Swap procedure was never agreed on | Fix the swap to one step: cue word then immediate switch |
| One partner is spent after Wall Balls | "The stronger one can just do more" leads to overload | Use a 40-30-30 three-swap pattern to distribute fatigue |
| Changing the split on race day | "We will figure it out" mentality | Write the split on paper and bring it to the venue |
| Losing track of distance on Burpee Broad Jump | No swap point was agreed on | Identify the 40 m mark on the floor before you start |
9. The one practice session worth doing
If you only do one pair-specific session before the race, make it an operations session, not a fitness test. The goal is to lock the hand-offs and commands, not to build more fitness.
Recommended session (60-75 minutes)
- Run 1 km x 2
Run together and confirm the target pace. Practice matching rhythm. - SkiErg or Row
Execute the planned distance-based swap. Verify the transition is smooth. - Sled Push (match race weight if possible)
Practice the 25 m swap procedure. Lock the cue word and movement flow. - Wall Balls 50-60 reps
Run through the planned swap pattern (e.g., 40-30-30) and check the rhythm. - Debrief (10 minutes)
Count how many times you stopped, where swaps were late, and where conversation was too long.
What you want to observe is not the time. It is where you stopped, where swaps were slow, and where the team rhythm broke. Those are the points that will cost you on race day.
10. What to log in HYFIT after the race
Doubles is harder to improve from memory alone than solo racing. Logging ownership ratios and perceived effort while the details are fresh makes next-race planning dramatically easier.
Logging template
| What to log | Example |
|---|---|
| Station ownership ratios | "SkiErg: A 600 m / B 400 m" "Wall Balls: A 40 / B 30 / A 30" |
| Perceived effort per run (RPE) | "Runs 1-4: easy / Runs 5-6: moderate / Runs 7-8: limit" |
| Stations where swaps were smooth | "SkiErg swap by distance worked well" |
| Stations where swaps were late or unclear | "Lost swap timing on Sled Pull" |
| Stations where one partner was overloaded | "B was more drained than expected after Wall Balls" |
| One rule to change next time | "Switch Wall Balls from 50-50 to 40-30-30" |
The key is to frame your notes as rules, not feelings. "Next time start Wall Balls at 40-30-30." "Keep run pace below 5:30 through Run 4." That format turns a race log into a usable plan.
11. Frequently asked questions
Q1Should HYROX Doubles teams split the work 50/50?
Not necessarily. The goal is not fairness for its own sake but a split that keeps the whole team stable through the next run and station. Lean into each athlete's strengths and design the split around total team time, not equal effort.
Q2Are Doubles weights the same as Open?
No. Doubles uses Pro-equivalent weights. Men Doubles Sled Push is 202 kg (Open is 152 kg), Wall Balls use a 9 kg ball (Open uses 6 kg), and other stations are heavier as well. Going in thinking "two people means lighter" leads to a painful surprise, especially on the sleds. Weight confirmation and targeted practice before race day are essential.
Q3What communication matters most in HYROX Doubles?
Three things matter most: who owns the next segment, the hand-off cue, and the opening run pace. Short preset phrases like "Switch," "You first," and "20 left" work far better than long conversations under fatigue. Agree on them before race day.
Q4Can pairs with a big fitness gap still do well?
Yes, but the plan matters more than usual. The experienced athlete can take the majority of sled work while the newer athlete handles more Row and SkiErg. The biggest risk is the stronger partner going all-out early and collapsing in the second half. Design the opening pace conservatively and protect the experienced athlete's energy for runs 6-8.
Q5Should we choose Doubles or Relay?
If you want to experience the full HYROX race, Doubles is the better choice. In Relay, each athlete only does 2 runs and 2 workout stations, so it is hard to get a feel for the race as a whole. However, Doubles uses Pro-equivalent weights. If either partner is concerned about handling that load, Relay is the safer entry point.
Q6What should we log after a HYROX Doubles race?
Log station ownership ratios, perceived effort on each run, where hand-offs were late, and which stations felt harder than expected. The key is to write rules for next time, not just feelings. "Switch Wall Balls to 40-30-30" is far more useful than "Wall Balls felt bad." That rule-based format gives you a real plan for the next race.
