Tips on Getting Rest
Being well rested for a long distance hike is really important. In the week before the hike, try to arrange your schedule so that you get several nights of full and restful sleep, but realize that the Friday night before hike day is not likely to be one of those 'good' nights. Remeber that the 100K starts at 3 AM, and even the 50K, starting at 10 AM, can induce pre-hike jitters!
While on the trail, be sure to pace yourself. Endurance is the key here, and the last mile and a half are uphill once you've crossed the bridge into Harper's Ferry. The good news? The Bolivar Community Center will be waiting for you with hot food, a place to rest, first aid, and most importantly, friends, family, and folks to help you celebrate your accomplishments!
