HYROX Doubles vs Singles: Which Should You Race?
Same course, same stations, same weights — and two completely different races. I have trained for both, and the honest answer to "which should I enter?" depends on three things: your running, your strength base, and whether you have the right partner. Here is the comparison without the marketing.
What changes — and what doesn't
| Singles | Doubles | |
|---|---|---|
| Running | 8 × 1 km, alone | 8 × 1 km — both partners run every metre, together |
| Station work | All of it, yourself | Shared: one works while the other rests, swap freely |
| Weights | Open or Pro loads | Identical Open or Pro loads — nothing is lightened |
| Pacing | Your race, your call | The pair moves at the slower runner's pace, every kilometre |
| Strategy | Split discipline | Split discipline plus a Team Sheet: who takes what, where you swap |
| Categories | Men's / Women's, Open & Pro | Men's / Women's / Mixed, Open & Pro |
The effort profile: where the suffering moves
The arithmetic is seductive: half the station work! The reality is subtler. In singles, stations wreck your legs and the runs become survival jogs. In doubles, you arrive at every run less damaged — so the pair runs them genuinely fast, and the race becomes a running race interrupted by near-maximal station efforts. Roughly half a typical solo finish is running; in doubles that share grows, because station time shrinks while the 8 km does not.
Translation: singles punishes a weak strength base, doubles punishes a weak engine. If your 1 km repeats are your weakness, doubles will expose it in front of a partner. If the stations are your weakness, doubles is merciful and singles is a long day.
How the times compare
The same clock time means very different things in the two formats:
| Finish time | As a solo time | As a doubles time |
|---|---|---|
| 1:00 | ~top 1% of solo athletes | top ~3% of doubles pairs |
| 1:15 | strong solo Open time | top ~28% of doubles pairs |
| 1:30 | solid first solo target | around the doubles median |
Converting your solo time to a doubles estimate
For an evenly matched pair, keep your run and transition time and scale station time by the shared-work factor 0.55. That works out to roughly 80% of a solo finish:
| Your solo finish | Doubles estimate (equal pair) |
|---|---|
| 1:10:00 | 55:50 |
| 1:15:00 | 59:49 |
| 1:30:00 | 1:11:47 |
| 1:45:00 | 1:23:44 |
Real pairs beat or miss this by how well they execute — mismatched runners lose time on every kilometre, and sloppy handovers give back the shared-work advantage in the Roxzone.
Who should pick which
Pick doubles if…
- You have a partner you can actually train with occasionally — or at least agree a Team Sheet with.
- Your engine outruns your strength: shared sleds and wall balls flatter runners.
- It is your first event and you want the experience with lower DNF risk. (New to the sport entirely? Start with the beginner guide.)
- You are coming back from injury or a layoff and full station volume is the risk.
Pick singles if…
- You want a clean, comparable personal benchmark — your time, nobody else's.
- Your running and strength are balanced; singles rewards the all-rounder.
- Scheduling with a partner is fiction. A doubles build needs at least occasional shared sessions.
- You are chasing a competitive placing and no available partner matches your level — a mismatched pair races below both athletes.
The decision checklist
- Partner? No reliable partner → singles. This question ends most debates.
- Matched pace? More than ~30 s/km apart on tired 1 km repeats → the faster runner sacrifices their race, so decide if that is the point.
- Weakness? Strength-limited → doubles helps you. Engine-limited → doubles exposes you.
- Goal? Finish and enjoy it → doubles. Benchmark yourself → singles.
- Still torn? Race both this season — the training transfers almost completely.
Either way, train for the one you pick
RoxDuo builds the plan backwards from your race date for both formats — doubles plans with synced partner sessions and a Team Sheet, or individual plans with station PB tracking. Decide the format, then train it specifically.

Is HYROX doubles easier than singles?
Easier to finish, not easier to race. Station work per athlete is roughly halved, but both partners still run all 8 × 1 km — and pairs run those kilometres faster because they carry less station fatigue. The suffering moves; it does not disappear.
How much faster are doubles times than singles times?
A well-matched pair typically finishes around 20% faster than the same athletes would solo, because station time is shared while running is not. Try your own numbers in the race time calculator.
Should a beginner start with doubles or singles?
Doubles is the friendlier entry: halved strength load, a partner managing logistics with you, lower DNF risk. Singles gives you a cleaner personal benchmark. Both are legitimate first races — see the beginner guide.
Are the weights different in doubles?
No. Open Doubles uses Open weights and Pro Doubles uses Pro weights — identical loads to the solo divisions. Only the sharing of station work changes.
Can I race both singles and doubles in one season?
Yes, and many athletes do — the fitness transfers almost completely. The main adjustments are pacing and station strategy, which a few pair sessions can rehearse.
