 Competitors get a new race number, and thus a new page requirement, at the start of each lap.The cut-off time for the 100-mile race is 60 hours overall, or an average of 12 hours per loop, and the cut-off for the 60-mile version of the race is 40 hours overall, which averages out to approximately 13 hours and 20 minutes per loop.Once a competitor has started a loop they are not allowed to receive any assistance, other than from fellow runners, until they have finished that loop.
