Start waves begin from 6:45 a.m. and aid stations along the course carry cut-off times for hikers off the pace. Letchworth is known as the Grand Canyon of the East, and the gorge rim trail gives this stop some of the best scenery on the Mammoth March calendar alongside a full day of sustained walking.
