About

Bogus 50/50 is held in Boise, Idaho, on September 26, 2026. Organized by Pulse Running, the event offers three trail distances with early staggered starts: a 50-mile at 5:00 a.m., a 50K (31 miles) at 6:00 a.m., and a 27K (about 16.8 miles) at 8:00 a.m. The name refers to the two ultra distances, and all three formats are run on trails.

If you have a marathon or two behind you and are ready for your first ultra, the 50K is the natural choice; the 50-mile is the next step for those with a 50K finish already in hand. The 27K gives newer trail runners a long, hilly race without ultra-distance commitment. Because the two longer races start before dawn, bring a headlamp and rehearse running in the dark at least once. A 16-week build with weekly climbs, back-to-back long runs for the 50-mile, and practice hiking steep sections will serve you well.
