Win the Ultimate SiS Endurance Fuel Bundle

Long runs, hard sessions, race days and everything in between – this one should keep you stocked for a while.

We’ve put together a £210+ Science in Sport endurance bundle loaded with fuel, hydration and recovery products, plus a bottle and stainless steel shaker.

And where flavour options are available, you get to choose what you actually want.

The winner receives

• SiS GO Energy Powder – 1.6kg

Hydration

• SiS GO Electrolyte Powder – 500g

Recovery

Choose your flavours

Where a product is available in multiple flavours, the winner can choose their preferred available flavour when the prize is ordered.

So you won’t necessarily receive the Blackcurrant, Berry, Orange or Vanilla options shown in our example imagery – those are simply the variants used when we priced the bundle.

All flavour choices remain subject to current Science in Sport stock and availability.

Only 299 entries

• £1.99 per entry
• Only 299 entries available
• Maximum 30 entries per customer

With a £217.50 bundle and only 299 tickets in the draw, we’re keeping this one deliberately tight.

Closing date & draw

• Entries close: Sunday 30 August 2026 at 9:00pm
• Automatic draw: Sunday 30 August 2026 at 9:15pm

The winner will be selected automatically and the draw will go ahead on the advertised date whether or not every ticket sells.

Prize terms

The winner will receive the eight Science in Sport products listed above, with a combined advertised value of £217.50 based on the prices used when the competition was created (or £200 cash alternative).
