For most first-timers, HYROX doubles is the smarter place to start: you split the eight stations with a partner, run all eight kilometres together, and finish fresher and more confident than you would solo. Choose singles first only if your goal is a personal benchmark time and you already have a solid aerobic base. As of 2026, doubles is the friendliest entry to the sport.
- In doubles you run all 8km together but split the station work, so the physical load is roughly halved on the stations.
- Singles requires you to complete all eight stations yourself, demanding more strength endurance and pacing discipline.
- THETA coaching data, 2024–2026, shows first-timers who start in doubles report a better experience and are more likely to return.
What is the real difference between doubles and singles?
In singles you do everything. Eight 1km runs and all eight stations alone. In doubles, you and a partner run every kilometre side by side, but you divide the reps and metres at each station between you. That splitting is the whole point: the sled, the wall balls and the lunges become far more manageable when shared. In my coaching experience, the running is what surprises doubles first-timers, because that part is not shared. You still cover the full 8km.
| Factor | Doubles | Singles |
|---|---|---|
| Running | Full 8km together | Full 8km alone |
| Station load | Shared, roughly halved | Full, all stations solo |
| Strength demand | Lower | Higher |
| Strategy | Splits and hand-offs | Pure self-pacing |
| Best for | First-timers, lower base | Benchmark seekers |
Why does doubles suit most beginners?
Because it lowers the barrier without watering down the experience. Sharing the stations means you are far less likely to hit a wall on the sled or blow up on the wall balls, which is exactly where solo first-timers struggle. You also get a partner to pace with, share nerves with, and hold you accountable in training. The running still challenges you, so you get an honest taste of the sport, but you finish able to walk out proud rather than wrecked.
When should you start with singles?
If your motivation is a clean, comparable personal time. A number that is entirely yours. Then singles is the right call, provided you have the base for it. You want a reasonable aerobic engine and enough strength to move the sled and complete the wall balls unbroken-ish before entering solo. Starting singles undercooked usually means a demoralising day of standing at the sled, which is why I steer under-prepared first-timers toward doubles first, then singles once the base is built.
- Assess your aerobic base. Can you run 8km with efficiency?
- Test the sled and wall balls; if they break you, start doubles.
- Pick doubles if your goal is experience and finishing well.
- Pick singles if your goal is a personal benchmark and you have the base.
- Either way, train compromised running. Both formats demand it.
"I always tell nervous first-timers to grab a partner and do doubles. You learn the race, you finish strong, and you come back hungry for a solo time. That is a far better first chapter than being broken by the sled alone," says George Wootten, Executive Coach, THETA.
Does the training differ for doubles and singles?
The engine work is nearly identical. Both formats demand a big aerobic base and compromised running, because you run the full distance either way. The difference is on the stations. Singles athletes need more strength endurance to carry the full load, while doubles partners should rehearse their splits and hand-offs so transitions are smooth. THETA's analysis of publicly logged elite training, 2023–2026, keeps confirming that running decides the race in both formats, so do not neglect the run just because a partner shares the stations.
Common questions
Is HYROX doubles easier than singles?
Doubles is physically easier on the stations because you split the reps and metres with a partner, but you still run the full 8km together. It is generally the friendlier format for first-timers while still being a genuine challenge.
Do you run the full distance in HYROX doubles?
Yes. Both partners run all eight 1km legs side by side; only the station work is shared. The running is the part doubles first-timers most often underestimate.
Should a beginner do doubles or singles first?
Most beginners are better starting in doubles because sharing the stations lowers the risk of blowing up while still teaching the race. Singles suits those chasing a personal benchmark who already have a solid aerobic base and station capacity.
Can you switch from doubles to singles later?
Absolutely, and many athletes do exactly that. Using doubles to learn the format before entering singles once their engine and strength are ready. It is a natural progression in the sport.
How do you split stations in HYROX doubles?
Partners divide each station's reps or metres, often alternating in blocks, and must both cover the running. Rehearsing your split ratios and hand-offs in training makes race-day transitions much smoother.
Does doubles training differ from singles training?
The aerobic and compromised-running work is nearly the same because both run the full distance, while singles demands more station strength endurance. Doubles pairs should additionally practise their splits and transitions together.
