50K.U.M

Event overview

The Keweenaw Ultramarathon in Houghton, MI is held on the Michigan Technological University Tech Trails. The event offers two distances: 50K and 25k. Registration closes on Fri, Nov 7 at 11:59 PM ET. The races are fully supported with aid stations and course marking. Time limits are an 8-hour cut-off for the 50K and a 7-hour cut-off for the 25k.

Racing will be timed through UltraSignup; there is no live tracking. Pacers are not allowed. All athletes must check in at every aid station by giving their bib number. The 50K requires a headlamp for the initial portion of the race.

Course and logistics

The course is based at the Tech Trails off the south side of Sharon Avenue across from Sherman Field. The 25k runs one loop of the course and the 50k runs two loops. The route is marked with neon flags on the right-hand side; flags on the left indicate the wrong way. Closed trails are marked with caution tape.
