Why SiS For Team Sky?

Science in Sport (SiS) is the official nutrition supplier to Team Sky; here’s some information on why they’re the no.1 choice to fuel our riders.

“With SiS there are no gimmicks, just elite performance products. They have a range of products for pre, during and post rides to support the riders to in training and on race day. This type of dedication to cyclist’s need-states helps us to plan world-class nutrition strategies. ” – Dr. James Morton, Head of Nutrition at Team Sky

SiS has three core product ranges: SiS GO, comprising of energy powders, isotonic gels, energy bars and hydration tablets; SiS REGO, a range of full spectrum recovery products; and REBUILD which includes the biggest innovation in protein for years – WHEY20. SiS products come in a variety of flavours, which is important to prevent boredom for the riders.


This broad range of products allows Team Sky to effectively plan their nutrition strategies, including when and what to consume during training and racing, with specific focus on the demands of each stage. For example, if the riders are in for a tough climb towards the end of a race, SiS GO Energy + Caffeine gels may be used before the climb to give them the mental edge. These gels come in both 75mg and 150mg versions. This detail helps tailor for the individual needs of Team Sky riders.

Every product that SiS provides is underpinned by the latest scientific research. This expertise is combined with feedback from elite athletes and nutritionists who work in the field, like Team Sky’s Dr James Morton. SiS also sponsors PhD students to provide the most up to date research surrounding physiology and endurance nutrition. This helps SiS to innovate and improve their range of trusted products.

“The philosophy behind Team Sky is marginal gains, this is something we have deeply in common with Science in Sport, they are committed to making cycling sports nutrition more effective and more convenient. Trust is also vital in elite sport and with SiS we have that. We trust the SiS manufacturing process and truly believe it’s second to none” – Sir David Brailsford, Team Sky Principle.


SiS’ dedication to athletes’ marginal gains fuelled the innovation of WHEY20. By recognising the need for protein on-the-go during long rides, when protein isn’t readily available from food, SiS developed this unique protein format to ensure the fast delivery of 20g of quality whey protein. By providing innovative products like WHEY20, Team Sky is able to take the Team’s nutrition to the next level. These small percentages can be the difference between winning and losing.


SiS has a world-class approach to banned substance testing. This is why elites like Team Sky have confidence that SiS pay attention to detail in delivering high quality sports nutrition. Unlike some nutrition brands, every product that comes out of the SiS facility is tested under Informed Sport against the 2017 World Anti-Doping Agency (WADA) list. Even the SiS GO Energy bars are hand rolled to ensure quality.
