This one is a marathon in distance only; think of it as a long day in the hills. You start at 8 a.m. on the soccer field beside the Patty Center at the University of Alaska Fairbanks, with birch leaves gone yellow and frost possible on the gravel. The route climbs about 1,800 feet up Ester Dome on ski trails and dirt road, then sends you on a rocky four-and-a-half-mile out-and-back near the summit before the chute, a third of a mile so steep the organizers tell you to be careful. Only the last stretch on Henderson Road is pavement. Total gain is roughly 3,300 feet, and the cutoff is ten hours, so walkers and hikers are welcome and plenty take that option. It is not a Boston qualifier and never will be. Register in April; the entry does not transfer or refund.
Starts and finishes on the soccer field by the Patty Center on the UAF campus; mostly trails and gravel roads with an 1,800-ft climb up Ester Dome, a roughly 4.5-mile rocky out-and-back near the top, the steep one-third-mile 'chute' descent, and paved Henderson Road at the end; 'about 3,300 feet of elevation gain and the same amount of descent'.
