how long is the long walk

The Long Walk involves an annual walking contest where participants must maintain a minimum pace of 4 miles per hour (6.4 km/h) without stopping, resting, or slowing down below that speed for more than 30 seconds. The walk starts near the Canada–Maine border and presumably follows a route like US Route 1 through Maine, New Hampshire, and potentially into Massachusetts. In terms of distance, based on route clues from the novel, the walk is about 310 miles long. The contest continues until only one walker remains alive. The walkers endure continuous walking with no breaks, and falling below the pace three times results in execution. The exact total duration depends on the survivors, but as they must maintain 4 miles per hour continuously, walking 310 miles would take roughly 77.5 hours (just over 3 days) if a walker could sustain the pace nonstop without getting warnings or breaks, which is practically impossible given the rules and conditions of the walk.
