A high volume of easily digestible calories and BCAAs become even more important during long efforts, because they can keep you from bonking and help reduce muscle damage while improving mental focus. This is why we recommend sticking to Roctane products for endurance activities like this, which deliver higher levels of BCAAs and electrolytes. We advise having and practicing your plan, but also advise being ready to adjust your plan as needed. This means carrying a few extra servings and a variety of flavors to entice yourself to keep fueling. Mix between sweet, savory and refreshing flavor for variety and try Summit Tea Roctane Energy Drink for a mild flavor you can sip all day. For an added boost of energy before hills or towards the end, look to carry flavors with caffeine.
