When should cyclists use Roctane instead of standard GU Energy Gel?

The GU Energy Roctane Gel Box of 24 is a full race-season supply of GU's premium gel, built for prolonged, high-intensity efforts where the original gel is not enough. Same 100 calories and 21g of carbohydrates per packet as the original, but with up to 3x the sodium (125mg vs ~60mg), 3x the BCAAs (1,425mg vs 450mg), and two amino acids not found in the original: taurine to maintain heart contractility and improve cardiac output during long efforts, and beta-alanine to buffer muscle acidity and delay fatigue onset during high-intensity work above lactate threshold. GU Energy Labs developed Roctane for athletes doing high-mileage training, intense stage racing, or ultra-distance events where muscular support and electrolyte replenishment are as critical as carbohydrate delivery.

Seven flavors across the box. Cold Brew is the standout: 70mg of caffeine per gel, double any other caffeinated Roctane flavor and the highest caffeine dose in the entire GU lineup. Use it strategically for early starts or the final hour of a long race. Blueberry Pomegranate, Vanilla Orange, and Salted Lime each carry 35mg. Cherry Lime, Strawberry Kiwi, and Sea Salt Chocolate are caffeine-free, ideal for steady-state fueling where you want clean energy without the stimulant. Take one gel 5 minutes before activity and one every 30 to 45 minutes during. Vegan, gluten-free, kosher, dairy-free. Always take with water.
