      Questions and next steps

      What runners ask about these 2 gels

      Does Precision Fuel & Hydration PF 30 have sodium?

      PF 30 lists 0 mg of sodium and Beta Fuel lists 15 mg.

      How many of each gel do I need for 60 g of carbs an hour?

      Two PF 30 gels (60 g) or 1.5 Beta Fuel gels (60 g).

      Can I take more than 60 g of carbs an hour with either gel?

      Yes, once your stomach is trained. Glucose on its own is limited to about 60 g an hour, and adding fructose is what lets a trained stomach handle up to about 90 g. Without practice in training, plan on about 60 g an hour.
