For women's HYROX doubles, wear the same light wicking race kit as a singles race, a race singlet or ventilated tank with close race shorts, because although you split the stations, you still run all 8 kilometres together and race for a similar duration in a hot arena. As of 2026, THETA's Women's Race Singlet and Race Short suit doubles as well as singles.

• In HYROX doubles, both partners run all 8×1km together, but only one works each station at a time while the other rests.
• You still race 60–90+ minutes indoors, so wicking, ventilated, light kit remains the priority.
• The rest intervals at stations mean brief cool-downs, so kit that stays light when soaked matters.

How does doubles change the kit demand?

Start with the number that does not move: 8 kilometres. In doubles you run every one of them side by side with your partner, so the running load on your kit is identical to singles. What changes is the 8 stations, which you split, giving you short rests while your partner works. Those rest windows are periods of lower output where sweat-soaked kit can feel cold, followed by a hard restart.

So the kit has two jobs across the same 60–90 minutes: stay cool during work and avoid turning into a cold, heavy layer during the rests. Light wicking fabric that stays light when soaked handles both. Kit that holds sweat becomes clammy in the rest windows and heavy for the runs.

Singlet, tank or tee for doubles?

The same three options rank the same way as singles. A race singlet is coolest for a hot arena, a ventilated tank gives a little more coverage, and a tech tee is warmest and best for cooler venues or personal preference. Because doubles still carries the full running load and a hot indoor environment, most athletes reach for the singlet or tank.

THETA's Women's Race Singlet is an ultra-light shell with laser-cut ventilation and a women's fit, and the Tech Tank uses open ventilation construction that stays airy through race sims and does not go heavy when soaked. Either works for doubles; the choice comes down to coverage preference and venue heat.

Do shorts matter differently in doubles?

Count the movements you still own personally: the sled push, the sled pull and 100m of lunges on your turns, all of them the movements that expose loose shorts. A close race short with fabric recovery stays clean through your station reps and does not ride up on the sled. THETA's Women's Race Short is built for exactly this.

The rest windows do not reduce the need for a good short, because on your turn you are working at full intensity. If anything, alternating means sharper, harder efforts, so kit that stays put through repeated deep hip movement is just as important as in singles.

"Doubles fools people into thinking it is easier on kit because you rest at the stations. You still run every metre, and your work sets are sharper because you know you get a break. The kit brief does not change, light, ventilated and secure, whether you race solo or with a partner," says the THETA coaching team.

How do you dress for a doubles race?

The preparation matches singles with one added step: coordinate briefly with your partner so transitions are smooth. Work through the five steps below.

1. Choose your lightest ventilated top for the venue heat, singlet or tank.
2. Pair it with a close race short that stays clean on the sled and lunges.
3. Warm up in a removable layer so you do not soak your race top early.
4. Agree station splits with your partner so you are not fumbling kit at swaps.
5. Use aid-station water on the skin during your rest windows to cool down.

Common questions

What should women wear for HYROX doubles?

Wear the same light wicking race kit as singles: a race singlet or ventilated tank with close-fitting race shorts. You still run all 8 kilometres and race in a hot arena, so ventilation, wicking and light-when-soaked fabric remain the priority. The rest windows at stations do not change the kit demand.

Is doubles kit different from singles kit?

No, the kit is essentially the same because you still cover the full running distance and race indoors for a similar duration. The only nuance is the short rests, where kit that stays light when soaked helps you avoid a cold, clammy layer. Choose light, ventilated, secure kit either way.

Do I still need good race shorts for doubles?

Yes, because you personally perform the sled push, sled pull and lunges on your turns at full intensity, and those movements expose loose shorts. A close race short with good recovery stays clean and does not ride up. THETA's Women's Race Short is built for this.

Should I wear more layers because I rest more?

Generally no, since the rest windows are short and you restart hard, so extra layers become heat traps and dead weight. Light wicking kit that stays light when soaked handles the brief cool-downs better than added fabric. Use aid-station water for cooling rather than adding layers.

Does a singlet work for doubles or should I cover up more?

A singlet works well for doubles in a hot arena because it is the coolest option and you still run the full distance. Choose a tank if you prefer more coverage without giving up much ventilation. The choice is about venue heat and personal preference, not the doubles format itself.

How do I keep kit comfortable across the rest windows?

Pick a fabric that wicks and stays light when soaked, so it does not turn cold and heavy while your partner works. Open, ventilated construction dries and breathes fast between efforts. Use aid-station water on the skin during rests to aid evaporative cooling.
