Keweenaw Ultramarathon

Keweenaw Ultramarathon takes place in Houghton, Michigan, on November 7, 2026, on the Keweenaw Peninsula at the top of the Upper Peninsula. The event offers two trail distances: a 50K (31 miles) and a 25K (15.5 miles). Early November this far north usually means cold conditions, so this is a late-season race for runners who do not mind layering up.

You will want to treat this as a rugged trail outing rather than a fast course. The 25K works well as a stepping stone for anyone with a trail half marathon under their belt, and the 50K is a good first ultra if you have already run a marathon distance in training. Focus your build on time on feet, hill repeats and at least a few long runs in cold or wet weather so that gear choices are settled before race morning.
