Who's going to The Guvnor Frozen 50?

Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The course

Where it goes multi-loop · 9 aid stations · rust marks a stop your crew can reach

The marquee distance at the Guv'nor: two loops of Governor Dodge State Park on horse trail, dirt single and double track and prairie path, about 31.4 miles with roughly 4,475 feet of climbing and a 9-hour cutoff. It's the only distance with crew access, a drop bag tent (Twin Valley, mile 15.8), and a pacer pickup (Horse Camp, mile 27.9, to the finish).

Terrain is a mix of horse trail, dirt single and double track and prairie path, with an average grade of about 136 feet of climbing per mile. In the event of substantial snow limiting access to parts of the park, the race switches to an approximately 8-mile accessible loop run 4 times, with aid at Cox Hollow (mid-loop) and Twin Valley (start/finish/split).

The race

What this one is

The Guv'nor Frozen 50 runs the horse trails, singletrack, doubletrack and prairie path of Governor Dodge State Park outside Dodgeville, Wisconsin, in early December, when the core trail season is over and winter is the other competitor. A 50K, a 25K and a 15K all start and finish at the Twin Valley Picnic Area, sharing the same climbs and the same aid stations, with roughly 136 feet of climbing a mile across the day. It's a cup-less, hunting-season race: runners carry their own hydration vessel and wear bright colors.
