HYROX DOUBLES VS SINGLES: WHAT CHANGES, AND WHAT IT MEANS AFTER 50

HYROX doubles vs singles comes down to one rule: in Doubles, you and your partner both run all eight kilometers together and split only the eight workout stations. The station weights are the same as the matching singles division, so a partner shares the reps, not the load. For a racer over 50, that makes Doubles a different race, not a half-size one.

HYROX Doubles vs Singles: What Actually Changes

Everything below comes from HYROX's own 2026/27 rulebooks for Singles and Doubles, which are posted on the HYROX website.

Both formats are the same race on paper: a 1 km run followed by a workout station, eight times, in a fixed order. The stations are SkiErg, sled push, sled pull, burpee broad jumps, rowing, farmer's carry, sandbag lunges and wall balls. In Singles, one racer does all of it.

In Doubles, the rulebook sets out a few specific differences:

• The runs are not split. Both team members must run together for the entire 1,000 m between stations. If one runs ahead, the rulebook applies a 1-minute penalty.
• The stations are split however you choose. The rulebook's example is a "You Go, I Go" row: one partner rows a self-selected distance, such as 250 m, then the other takes over, and you repeat until the 1,000 m is done.
• You enter and leave each station together. The station cannot start until both partners are there, and the partner who is resting must stay on their feet. Kneeling, sitting or lying down is not allowed.
• Staying together is enforced. A team with more than three penalties for not staying together is ruled out of competition and does not get a ranking.
• Your finish time is the slower partner's. The official time is recorded when both partners have crossed the line.

The Weights Are Not Halved

This is the part that surprises people. Each Doubles division uses the same station loads as a Singles division:

• Doubles Women uses the Women Open loads: a 102 kg sled push, 78 kg sled pull, two 16 kg kettlebells for the farmer's carry, a 10 kg sandbag and a 4 kg wall ball (all sled weights include the sled).
• Doubles Men, Doubles Women Pro and Doubles Mixed use the Men Open loads: a 152 kg sled push, 103 kg sled pull, two 24 kg kettlebells, a 20 kg sandbag and a 6 kg wall ball.
• Doubles Men Pro uses the heaviest loads: 202 kg, 153 kg, two 32 kg kettlebells, a 30 kg sandbag and a 9 kg wall ball.

The point for a mixed team: the woman on the team works with the Men Open sled, kettlebells, sandbag and wall ball for her share of the stations. In Women Open Singles, she would use the lighter set. If one partner can't move the sled at all, splitting the meters doesn't solve that.

What That Means for a Racer Over 50

The running is the half of the race a partner can't take off your hands. In the first published HYROX study, eleven recreational athletes ran a simulated Open race from the University of the Bundeswehr Munich in 2025. Median finish time was 86.5 minutes, and 51.2 of those minutes were spent running, against 32.8 minutes at the stations. Faster finish times were associated with a higher VO2max, more endurance training and lower body fat. That was a Singles race, but the Doubles rules mean each partner still covers every one of those running meters.

The one HYROX injury study points the same way. In a 12-week cohort of 89 HYROX athletes from the University of Bath, published in 2026, most injuries (73%) were overuse injuries, and the knee and lower leg carried the greatest burden. The authors described that pattern as consistent with the sport's running load. Splitting the stations does not change your running load in Doubles.

What a partner does change is the station work: fewer reps per person and a rest while your partner works. The rulebook also sets age groups for Doubles by the team's average age on race day, in five-year steps from under 24 up to 85-89, so a 52-year-old and a 58-year-old race as a 55-59 team. Teams aged 60 and over qualify for the World Championships through the Open division only.
