Is the SiS Beta Fuel + Electrolyte Box of 30 Worth It for Summer Racing?

The SiS Beta Fuel + Electrolyte Gel Box of 30 gives you a full season's supply of the most complete gel in the SiS lineup. Each gel delivers 40g of dual-source carbohydrates alongside 150mg sodium, 19mg potassium, and 6mg magnesium, covering both the energy demands of sustained high-output efforts and the electrolyte losses that compound in the heat. At 30 gels, you have enough to fuel multiple long races and all the training that builds into them without managing reorders mid-block.

Best value per gel for athletes who have already tested Beta Fuel + Electrolyte and made it their race-day gel. Available in Lemon and Mango. A straightforward choice for anyone who races long in warm conditions and wants one gel that does the full job.
