Win the Ultimate SiS Performance Bundle

Win the Ultimate SiS Performance Bundle

Big training weeks need plenty of fuel.

We’re giving one winner a complete Science in Sport Performance Bundle worth £216.30, packed with nutrition to keep you fuelled, hydrated and ready for your next session.

Whether you’re putting in the marathon miles, getting ready for HYROX or spending your weekends out on the bike, there’s plenty here to keep you stocked up.

What’s included?

One winner takes home the lot:

• SiS GO Isotonic Energy Gels (30 Pack) – Easy-to-carry carbohydrate fuel for long runs, rides and race days.
• SiS GO Electrolyte Powder (500g) – Carbohydrates and electrolytes together in an easy-to-mix drink.
• SiS Double Wall Stainless Steel Shaker (750ml) – An insulated shaker for your recovery drinks.
• SiS Pro Sports Bottle (800ml) – A training bottle for the gym, road or trail.
• SiS REGO Rapid Recovery (1.5kg) – A protein and carbohydrate recovery shake for after tough sessions.
• SiS GO Energy Powder (1.6kg) – A carbohydrate drink mix for fuelling longer training sessions.
• SiS HYDRO Tablets (3 Tubes) – 60 electrolyte tablets in total, ideal for staying on top of hydration.
• SiS BETA Fuel 80 (15 Pack) – High-carbohydrate drink sachets designed for longer endurance sessions.

That’s eight different product lines worth £216.30, all going to one winner.

Where products come in different flavours, the winner can choose from the options available when we arrange their prize.

Fuel. Hydrate. Recover.

From getting your carbs in before a long run to keeping your hydration topped up and refuelling afterwards, this bundle covers the lot.

It’s the kind of nutrition you’ll actually get through if you’re training regularly, and a decent amount to have stocked up ready for your next race.

Prefer the cash?

The winner can choose £150 cash instead.

Although we’d much rather see you take the full SiS bundle, get it into your training routine and put it to good use.
