Keweenaw Ultramarathon : Houghton, MI

The Keweenaw Ultramarathon is a trail event held on the Michigan Technological University Tech Trails in Houghton, Michigan. The event offers two distances:

  • 50K
  • 25K

The 25K follows a single loop of the course; the 50K runs the same loop twice. The 50K requires a headlamp for the early portion of the race. The route is marked with neon flags on the right-hand side and closed trails are marked with caution tape; seeing flags on the left indicates the wrong direction.

Aid stations are located at multiple mile points and will supply water, drink mix, and typical ultra foods. All athletes must check in at every aid station encounter by reporting their bib number. Runners may access personal gear or drop bags at the trailhead community room, under a tent, or in their cars once checked in at the trailhead aid station.

The event uses chip timing through UltraSignup and does not provide live tracking. Pacers are not allowed. Time limits are enforced for safety due to the course's remote nature: the 50K has an eight-hour cut-off and the 25K has a seven-hour cut-off. Parking is available at the main trailhead and nearby overflow areas. Event merchandise includes club t-shirts sold on race day for a stated price.
