Yes, but less than people expect. In doubles you still run the full 8 km, while station work is shared — so the day is similar in length but spikier, with short recoveries while your partner works. That pattern tends to make a heavy stomach more noticeable, not less, so the usual advice holds: familiar, carbohydrate-led, low fat and fibre, rehearsed in a doubles simulation rather than solo.

Does HYROX doubles change how I should eat? Yes, but less than people expect. In doubles you still run the full 8 km, while station work is shared — so the day is similar in length but spikier, with short recoveries while your partner works. That pattern tends to make a heavy stomach more noticeable, not less, so the usual advice holds: familiar, carbohydrate-led, low fat and fibre, rehearsed in a doubles simulation rather than solo.
Plan both athletes' meals at order.smashmeals.com
HYROX publishes one fixed format: eight 1 km runs alternating with eight workout stations, so every athlete covers 8 km of running plus 8 stations. In the doubles format the running is still covered by both athletes, while the station work is split between partners. The total time on the floor is often similar to a solo race, but the internal structure is different: short bursts at a higher relative intensity, punctuated by brief standing recoveries while your partner works.
That structure has two nutrition consequences. Spikier efforts with short recoveries are the worst-case scenario for a full stomach, and the standing recoveries make people more aware of how they feel, which amplifies any gut discomfort they would have pushed through solo.
Nothing in the literature addresses paired racing specifically, so the underlying principles carry over. The 2026 consensus discussion on carbohydrate availability supports adequate availability for high-intensity work, and the contemporary carbohydrate review warns against transplanting one intake figure across different event demands.
For the training block behind a doubles race, the ISSN position stand on protein and exercise remains the daily reference point at roughly 1.4–2.0 g/kg/day for most exercising people.

Our kitchen is 100% dedicated gluten-free because some people need it to be — coeliac disease, diagnosed gluten sensitivity, or a household that simply eats gluten-free. Removing gluten is not a performance strategy in itself, and there is no good evidence it improves output, recovery or inflammation in athletes without a medical reason. In doubles there is one extra practical point: do not let a shared pre-race meal put a coeliac partner in a venue where nothing is safe. Separate, planned food avoids the problem entirely.
