Hyrox Doubles
Split Planner

Give each station to the partner who is faster at it, but share the work rather than giving them all of it. A rested partner works faster in short blocks, so the best split is usually uneven but not extreme. Enter both partners' solo times in the planner for a rep and distance split for each of the 8 stations.

Yes. Both partners must run together for the whole 1 km between stations. If one runs ahead, a 1-minute penalty applies, and more than 3 penalties for not staying together makes the team Out of Competition. The stations are the only place the work can be divided.

It is the doubles station format: one partner works while the other rests, and they switch at distances or rep counts they choose themselves. For a 1,000 m row, for example, one partner might row 250 m, then swap, repeating until 1,000 m is covered. The resting partner must stay on their feet.

The Doubles rulebook lets partners choose their own switch points and does not set a per-partner minimum for a station. Both partners must enter the station together and leave together once the full distance or reps are complete, so the weaker partner still has to be present, resting on their feet.

A lot compared with going solo. At median level, Doubles Men finish the stations far quicker than Open Men: wall balls 6:28 solo versus 4:10 as a team (36% faster), and sled push 2:52 versus 1:45. Within a team, picking an uneven split over 50/50 typically saves seconds per station, not minutes.

The heavy, high-fatigue stations. Based on median times, the five biggest gains are Burpee Broad Jumps, Sled Push, Wall Balls, Sled Pull, Sandbag Lunges, led by Burpee Broad Jumps at 41% faster as a team than solo. RowErg benefits least (7%) because pacing a 1,000 m erg is less about fatigue from the reps.

Usually, but not all of them. The planner caps any split at 75/25 because the model is built from pairs of similar ability, and a stronger partner who does everything is simply racing solo and gives up the rest benefit. For wall balls with times of 5:30 and 7:00, the planner suggests 60 reps and 40 reps.

There is no fixed rule, because the rulebook lets partners pick their own switch points. Each hand-over costs a few seconds and breaks rhythm, so fewer, larger blocks usually beat switching every few reps. The planner gives the total share per partner; split each share into blocks that keep both of you below the point where your pace drops.

In Mixed Doubles both partners use the Men's Open weights: a 152 kg sled push, 103 kg sled pull, 2 x 24 kg farmers carry, 20 kg sandbag and 6 kg wall ball. Only the wall ball target differs, at 3.00 m for the man and 2.70 m for the woman. See every division in the Hyrox weights table.

The ball must be passed by letting it hit the floor or by handing it between partners. A flying transition, where one partner throws and the other catches the ball in the squat and keeps moving, is not allowed and counts as a no-rep. Plan wall ball blocks so you can swap cleanly rather than rushing the exchange.

Treat it as a guide, not a promise. The fatigue exponent for each station is derived from real Open and Doubles median splits, which compare teams with solo athletes rather than the same athletes in both formats. The tool ignores hand-over time and caps splits at 75/25, so real savings will usually be a little lower.

No. In a Relay each of the four athletes runs 2 x 1 km and completes two whole stations, so you assign whole stations rather than splitting reps. The doubles and relay guide covers how to assign legs.

No. The planner runs entirely in your browser. The times you enter are not uploaded, stored or linked to an account, and there is no signup.
