Referee Felix Zwayer went down with cramp during the World Cup game of USA vs Australia this weekend ⚽

A reminder that it's not just the players who need to get their fuelling and hydration right ⛽

Whether you're covering every blade of grass, coaching from the sidelines, or just trying to get through a long day in the heat, your body still relies on the same fundamentals: fluids, electrolytes and energy.

You don't need to be a professional athlete to feel the impact of poor hydration. And you definitely don't need to be a professional athlete to benefit from getting it right.

Fuel well. Hydrate well. Perform better.

Is it coming home? ⚽

Tonight is England's time to take the stage at the World Cup against Croatia.

For these two teams and so many more in the tournament, the travel and various time zones mean players need to be well hydrated and fuelled with the right nutrition for matchday to perform at their best.

"The Ekiden relay is really a beautiful demonstration of teamwork and how sport can bring people together, to support each other towards one goal."

-

Last Friday, 35 teams, including Team SiS, tackled 112km along the Thames Path 🏃‍♀️🏃‍♀️

We loved fuelling UK Ekiden, and embracing the incredible Japanese culture that came with it - we can't wait for the next one!

Some rides remind you why you started cycling in the first place 🌄🚴

But when the landscape is this big, your fuelling needs to match the ride.

Fuel every climb with SiS.
