HYROX Doubles vs Singles: How to Train Differently

Doubles is not "easier Singles." It is a different race.

The most common assumption I hear from first-time HYROX racers considering Doubles is that it is just Singles divided in half. The runs are still all 8 km per athlete. The race time is still 60 to 100 minutes for most teams. And the stations require different tactics: who pushes, who pulls, how do you split the wall balls, when does the partner take over on the lunges. Doubles is a tactical event, not a watered-down version of Singles.

The good news for first-time racers: Doubles is often easier to enjoy and finish strong than Singles. The partner accountability stops you from blowing up early. The split station volume reduces total grip and quad fatigue. And the social element of running with someone often produces better pacing than racing alone. Many of the first-time racers I coach at Persistence Athletics in Belltown start with Doubles for these reasons.

But to race Doubles well, you train for Doubles. The programming is different from Singles, the partner work is different, and the mental approach is different. This guide covers all three.

Singles vs Doubles: the format breakdown

Both formats are the same 8 km of running broken into 1 km segments, with 8 stations between them. Same stations, same order, same total work for the team. The differences:

Singles. One athlete does everything. 8 km of running plus all 8 stations. Race time 60 to 120 minutes. Mental load is high (you have only your own pacing decisions), physical load is high (no sharing of station work).

Doubles. Two athletes do it together. They run the 8 km side by side (must stay together within roughly 10 m). They split the station work. Race time 50 to 100 minutes for most teams. Mental load is shared (your partner can pull you back from a too-fast pace). Physical load per athlete is lower on stations, same on runs.

Total work for the team in Doubles is identical to Singles. The split is what changes. A Doubles team is not racing half a HYROX, they are racing all of it with two engines.

There are also Doubles divisions: Mens Doubles, Womens Doubles, and Mixed Doubles (one male and one female athlete). Mixed has additional considerations because the strength and run-pace differences between partners can be larger. The principles below apply across all Doubles divisions but are most relevant to same-gender pairs.

How the work splits at each station

This is where Doubles tactics live. Most stations have multiple legal split options. Picking the right one for your team is a 30-second to 2-minute time difference per station.

Station	Singles work	Doubles split (typical)
1. SkiErg (1000 m)	Solo	Split 500 m / 500 m or alternated
2. Sled Push (50 m)	Solo	One athlete does the full push, partner rests
3. Sled Pull (50 m)	Solo	One athlete does the full pull, partner rests
4. Burpee Broad Jumps (80 m)	Solo	Split or alternated
5. Row (1000 m)	Solo	Split 500 m / 500 m or alternated
6. Farmers Carry (200 m)	Solo	Split distance or alternated
7. Sandbag Lunges (100 m)	Solo	Split distance or alternated
8. Wall Balls (100 reps Mens / 75 Womens)	Solo	Split reps (commonly 50/50, can adjust)

A few notes on tactics:

Sled push and pull (stations 2 and 3). These usually go to whoever is stronger on each. If both partners are equal, alternate. The partner not on the sled gets 30 to 90 seconds of recovery. Use it. Get your breathing down before the next run.

SkiErg and Row (stations 1 and 5). Splitting 500 m / 500 m is the most common pattern. The first athlete goes hard, the second matches. The handover is 5 to 10 seconds. Practice it.

Burpee broad jumps (station 4). Alternating every 5 reps or splitting at the halfway point both work. Alternating gives more recovery, splitting is faster transitionally. Test both in training.

Wall balls (station 8). This is where Doubles teams either close the race or fall apart. The partner with stronger wall balls should take 60 to 70 percent of the reps if it is unbalanced. Equal teams go 50/50. Plan it in training.

The transition between athletes counts toward race time. A team that has practiced transitions saves 30 to 60 seconds per station, which is 4 to 8 minutes across 8 stations. That is the gap between a top-half finish and a top-quarter finish.

Programming differences: Singles vs Doubles training

The training for Doubles is different from Singles in three specific ways.

1. Station volume per session is lower per athlete, but transition speed is higher. Singles training builds full-volume station endurance: 50 sled pushes, 100 wall balls, full SkiErg meters. Doubles training builds split-volume work plus transition fluency. A Doubles workout might be 50 wall balls split between partners, with the goal of zero transition delay. Total reps for the athlete are lower, but transition skill is higher.

2. Run pacing is matched, not individual. A Singles athlete picks their own run pace. A Doubles team has to find a shared pace that both partners can hold for 8 km. Most teams pace at the slower athlete's sustainable pace, plus or minus 5 percent. Practice this pace together in training. Do not let the faster athlete drag the slower one beyond sustainable.

3. More partner-specific work, less solo conditioning. Singles training is heavily individual. Doubles training has to include partner workouts, transition drills, and tactical rehearsals. Expect to spend at least 30 to 40 percent of your final 4 weeks of prep training with your partner, not solo.

A typical 12-week Doubles prep block looks like this:

• Weeks 1 to 4: Base building. Mostly solo work for both athletes. Aerobic base, station strength, run volume. Same as Singles prep at this phase.
• Weeks 5 to 8: Partner integration. Add 2 partner workouts per week. Practice splits on each station. Find your shared run pace.
• Weeks 9 to 11: Race-pace simulations. 3 to 4 partial sims at race pace, with full transition practice. One full sim 2 to 3 weeks out.
• Week 12: Taper. Reduce volume, hold sharpness. Last partner workout 5 to 7 days before race day.

The partner workouts are the difference. Singles racers can prep solo. Doubles racers must train with their partner.

How we coach Doubles at Persistence Athletics

Persistence Athletics in Belltown runs a HYROX program with a Saturday class that supports both Singles and Doubles racers. Doubles teams typically pair up early in their prep block and attend Saturday classes together.

The most common mistake I see in first-time Doubles teams is mismatching pace. One athlete is a 4:30/km runner, the other is a 5:30/km runner, and they try to race together at 5:00/km. Both end up off their sustainable pace. The faster athlete is bored, the slower athlete is hanging on. By kilometer 5 the slower athlete is cooked and the team falls apart.

The fix is to pick partners within 10 to 15 percent of each other on run pace. If you are a 5:00/km racer, your partner should be 4:30 to 5:30/km. Closer is better. If you are mismatched by more than 20 percent, the team will not race well together regardless of fitness.

We also coach explicit station tactics. Two weeks before race day, every Doubles team sits down with me or with our personal training coaches and we map out who does what at each station. Some teams alternate, some split halfway, some go in lopsided ratios where one partner is stronger. The plan goes on paper. On race day, the plan is not improvised.

The mental side of Doubles is also different. In Singles, you only have to manage your own state. In Doubles, you also manage your partner's state. If your partner is breathing hard, you slow the run. If they are talking and joking, you pick up the pace. Reading your partner is a skill. The teams that race well are the ones who have practiced reading each other across multiple sims.

The 5 rules for picking and training with a partner

These are the rules I give every athlete who is considering Doubles.

1. Match pace within 15 percent. Run pace is the most important match factor. Strength differences can be managed with station tactics. Pace differences cannot.

2. Pick someone you train with already. A partner you already train with knows your patterns and you know theirs. A new partner introduces unknowns. If you must pick a new partner, train with them for at least 8 weeks before the race.

3. Communicate during training. Talk about pacing, talk about how you feel, talk about the plan. Doubles teams that go silent in training go silent on race day, and silent teams do not race well.

4. Practice transitions explicitly. At least 3 race-pace sims with full transition practice. Time your handoffs. The 5-second handoff is normal, the 30-second confused handoff costs you the race.

5. Plan station splits 2 weeks before race day, not on race day. Each station has a tactical decision. Map them all in advance. Adjust based on the final pre-race sim. Do not improvise.

Teams that follow these rules typically come in within 5 to 10 percent of their target time. Teams that freelance the partnership routinely lose 10 to 20 minutes to coordination problems.

Frequently Asked Questions

What is the difference between HYROX Singles and Doubles?

Singles is one athlete completing all 8 km of running and all 8 stations alone. Doubles is two athletes completing the same race together, with running done side by side and station work split between partners. Total work is the same. Per-athlete work is roughly half the station volume and the same running volume in Doubles.

Is HYROX Doubles easier than Singles?

Easier per athlete in absolute work, but not necessarily easier to perform well in. Doubles introduces partner pacing, transitions, and tactical decisions about who does what station. The runs are still 8 km per athlete. Top Doubles teams are often faster than the same athletes would be racing Singles, but coordination matters. A poorly matched pair can be slower than either athlete solo.

How do you train differently for HYROX Doubles?

More partner-based metcons, more station-volume work split with a partner, more tactical practice of transitions. Less single-station endurance training (you are sharing reps), more attention to short bursts and transition speed. Run training is similar between formats. Practice the actual race transitions at least 3 times in the final 4 weeks of prep.

How should I pick a HYROX Doubles partner?

Match conditioning and run pace within 10 to 15 percent. Then look at communication and reliability. A partner who shows up to training, takes feedback, and pushes their own pacing is more valuable than a slightly faster partner who is unpredictable. Avoid mismatching by more than 20 percent in fitness, the faster athlete will end up doing too much and the team will underperform.

Can a beginner do HYROX Doubles for their first race?

Yes. Doubles is often the better entry point for first-time HYROX racers. The split station volume reduces total fatigue, the partner accountability helps with pacing, and the social element makes the race more enjoyable. Many of our first-time racers at Persistence start with Doubles and move to Singles in their second or third race.

What stations are easier or harder in Doubles?

The sled push and pull are split (one push, one pull, partner choice). Wall balls are split (typically 50/50, but can be different ratios). Sandbag lunges and farmers carry are usually split distance. Burpee broad jumps and SkiErg can be split or alternated. Plan station splits in training, not on race day. Each station has tactical choices about who does which portion.
