Course, aid, and access
The 50K is an out-and-back route that follows Baker Lake Trail #610 along the lake’s east shore. Runners leave a short paved section that crosses the Upper Baker Dam, then a gravel approach to the trailhead. The one-way trail distance is about 13.3 miles, with rolling single-track, old growth forest sections, footbridges, log crossings, and views along the lake. Total elevation change is about 6,800 feet (roughly 3,400 feet gain and 3,400 feet loss). Aid on the trail includes several water-only stations and a halfway aid station at about 15.6 miles with water, sports drink, gels, snacks and toilets. The finish area offers prepared food and beverages. Spectator access is possible at one point on the far north end of Baker Lake Road; a forest service pass is required for that access.
