The Amazon Spring Sale is into its last few hours which means there's not long left to grab a bargain. Over the past seven days we've seen some fantastic health and fitness deals, from cut-price running headphones to discounted Garmin watches and treadmills. But if there's one offer you don't want to miss before the clock strikes midnight, it's 33% off Science in Sport's Beta Fuel Gels.
Packing in a whopping 40g of carbohydrates per gel (almost double some products on the market), these were voted the best high carb gels in our 2025 Sports Nutrition Awards. And at just £9.99 for a pack of six, this is the perfect time to stock up for marathon season.
SiS Beta Gels have a consistency slips down easily and provides a welcome stamina boost. Crucially, it also has a 1:0.8 blend of maltodextrin to fructose to protect against digestive disasters and enable speedy absorption — because no one wants a mid-race dash to the portaloo.

The catch? Beta Fuel Gels don't come cheap, which is why I recommend stocking up for your future long runs and races while the price is low.
If you prefer to drink your carbs, rather than take them on in gel form, the Beta Fuel Carb Powder is also 32% off, down to £22.63.
