      Questions and next steps

      What runners ask about these 2 gels

      How many SiS Beta Fuel gels should I take an hour?

      Taking 1.5 gels an hour, or 3 gels every 2 hours, gives you 60 g of carbs, and 2 gels an hour gives you 80 g. C30 takes 2 gels for 60 g and 3 gels for 90 g.

      Is 40 g of carbs in one gel too much?

      The limit that matters is your hourly total: about 60 g an hour for an untrained stomach, rising to about 90 g with fueling practice. A 40 g gel fits within either, as long as the hour adds up.

      Do C30 and Beta Fuel both mix glucose and fructose?

      Yes. Both use maltodextrin and fructose. C30's ratio is 2 to 1 and Beta Fuel's is 1 to 0.8, and that mix is what lets a trained stomach go past about 60 g an hour.
