Start Time and Cutoffs

This is Wisconsin in January and we’ve tried to allow time in this unforgiving environment. But be warned. Finisher rate will be seriously low due to the weather. Plan. Plan. Plan.

The race will begin at 9am Saturday.

There is an overall race cutoff of 24 hours. There are two hard cutoffs for runners to hit. The Highway P cutoff will be 8pm. The 45 mile Mauthe Lake cutoff will be 4am.

Information Briefings

There will be an athlete and volunteer briefing in December 2024 for the 2025 event.


In January 2023 an incredible volunteer offered up their time to take photos while on the course. In 2025 we do not have plans for access to a photography on event day. While we will try to capture highlights from the race, we cannot guarantee that a photo of you will be captured on course. We apologize for any inconvenience this may cause.
