From the feedback we get, many appreciate the aid station at Mile 10.5 and others have asked why there isn't one available earlier. The answer is that we cannot provide anything but water on the trail portion of the course. If you desire gel or sports drink prior to Mile 10.5, we suggest you carry it with you. However, whatever you bring in the trail, you must bring out. Please do not throw your trash on the trails. LEAVE NO TRACE!
