Science in Sport becomes fuel partner for Nike's After Dark Tour

Science in Sport has been named the official performance fuel and hydration partner of the Nike After Dark Tour, a series of seven night-time running events staged around the world in 2026. The calendar runs from Shanghai and Sydney through Mexico City, London, Los Angeles, Manila and Mumbai, and will reach more than 55,000 runners.

As part of the deal the brands are launching a co-branded SiS x Nike nutrition range, which the brand says is the first time Nike has created a co-branded nutrition line with a performance nutrition partner. It spans energy, hydration and recovery, and notably includes bespoke recovery products developed with female nutrition in mind. Every participant receives a race-specific Race Pack, with a limited range on public sale in the UK, US and Australia from 4 September.

"What makes this partnership different is that we've started with the runner, not the product," said Dan Lampard, chief commercial and operating officer at Science in Sport. "It brings the performance nutrition principles used at the highest level of sport into a simple, accessible experience for tens of thousands of runners."

Beyond the events, the tie-up extends into education through a dedicated microsite along the participant journey, giving SiS a global-scale platform for its science-led fuelling expertise.
