      Questions and next steps

      What runners ask about these 2 gels

      How much sodium is in NEVERSECOND C30 compared with GU Liquid Energy?

      C30 has 200 mg a gel and GU has 75 mg a packet, so C30 has about 2.7 times as much.

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

      Two C30 gels (60 g) or 2.5 GU packets (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.
