Same gel. Same 45g of carbohydrates in a 2:1:1.5 ratio, same 343mg of sodium. The only addition: 75mg of caffeine. Designed to slot into the second half of your race — when focus fades and effort climbs. Caffeine peaks 45–60 minutes after intake, so time it before the moment you need it, not during. Use 02 During Gel as your base. Use this when it counts.
