Take a package of GU, put it through a year of hard training, eating right and you'll come back with GU Rocktane. Roctane is specifically formulated for your most intense training and racing. If you face a hard, multi-hour training session or race (think marathons, ultra-marathons, Iron-distance triathlons, 100-plus-mile bike rides and adventure races), take one-to-two Roctane gels 15 minutes prior to the start, followed by an additional packet every 30-45 minutes along the way. If you compete in short bursts of all-out efforts (think track meets or crew regattas) then go with a packet of Roctane 45 and 15 minutes before, as well as immediately after, your event.
Added amino acids to slow lactic acid production, aid recovery and to bounce back from the edge are what sets Roctane apart from your ordinary gels.
Roctane Ultra Endurance Energy Gel designed for the hardest working athletes in sports.
