Routes, navigation and checkpoints

The 50-mile, 50 km and 21-mile routes are waymarked at major junctions; the 100-mile route is unmarked for the first half and requires use of the GPS trace. Compulsory kit includes an emergency map or backup GPS device. There are 13 checkpoints on the 100-mile route and 6 on the 50-mile route; shorter races have multiple checkpoints. Drop bag availability varies by distance.
