Hands down, the Ultimate Direction Thunderbolt Hydration Waist Belt is the most versatile belt for runners that need enough liquid (water/sports drink) and fuel to go that extra distance - whether a marathon or a 50K. Because on race day, runners that lose precious seconds to competitors from pinching those annoying water station cups might have to settle for a pair of socks versus all the money.
