Every body processes a gel differently

The boxes of 20 you buy today assume one flavor, one brand, one formula. If it doesn't agree with your stomach or your caffeine tolerance, you're left with 19 gels you'll never eat.

You know it as "hitting the wall," and it shows up more often because of the wrong gel than because of too little training.

Carbs per hour (> 90 min effort)60–90 g
Sodium loss through sweat300–700 mg/L
Gels in a standard box20 pcs, 1 flavor
Gels in your gel box8–12 pcs, mix freely

Every ride, every run, your fuel

Whether you're training for your first 10K or riding your hundredth sportive, The Fuel adapts to what you need, not the other way around.
