This depends on your start time, your walking speed, and how many rest stops you take and for how long. The average finish time is about 12 hours. We will be at the start from 7 a.m. to 8 a.m. and at the finish from 5 p.m. to 10 p.m. If you arrive after 10 p.m., we can mail your certificate. On May 1, the sun will set at 7:51 p.m., so please be prepared to walk in the dark if you won’t be finished by then. Our volunteers along the route leave by 8 p.m.
