On the calendar
The date is set. Entry has not opened. As of this research (August 2026) the official site and UltraSignup still show the completed 2026 edition (June 13-14, 2026, UltraSignup did=128736) and have not yet published a 2027-specific page. The 2027 date is INFERRED from the race's own stated pattern, 'Race is always the second Saturday of June' (confirmed on the homepage), which independently reproduces June 13, 2026 for the just-run edition. The second Saturday of June 2027 is June 12. This was cross-checked (not cited, per house rules on ultraracecalendar.com) against ultraracecalendar.com, which independently lists 'Kettle Moraine | La Grange, United States | Jun 12-13, 2027 (Sat-Sun)', matching the computed date. No 2027 UltraSignup event id exists yet; each year gets a new one (2025=did 122592, 2026=did 128736).

The course
Where it goes
out and back · 11 aid stations
A non-competitive, night-time out-and-back over the southern half of the 100-mile course: Nordic Trailhead south to Rice Lake and back. Explicitly designed to let a runner pace or accompany a 100-mile runner over the race's final, hardest stretch; many Fun Run entrants deliberately start when 'their' 100-miler comes through Nordic rather than at a fixed clock time.
This course is not separately charted by the race; its stations and mileage are the second half (mile 63.9 to 100.5) of the official 100-mile chart, re-zeroed to start at 0.0 (inferred arithmetic, e.g. Rice Lake at 82.2 - 63.9 = 18.3 mi for this course). The 36.6 mi total from that arithmetic is close to, but not identical to, the race's own '38 mile' branding and to the GPX-measured 36.42 mi -- none of the three figures reconcile exactly, and none is treated as authoritative over the others.
The race
What this one is
A 100-mile (with 100K, 50K and 38-mile companion distances) trail race entirely on the Ice Age National Scenic Trail and connecting trails in the Kettle Moraine State Forest's Southern Unit, run as two out-and-back sections from the Nordic Trailhead near Whitewater/La Grange, Wisconsin. A Western States 100 qualifier and part of the Midwest Grand Slam of Ultra-running.
Started in 1996 by Kevin and Kris Setnes, who race-directed for 6 years. Tim "Timo" Yanacheck and Jason Dorgan then co-RD'd until 2018. Michele Hartwig of Ornery Mule Racing has directed the race since. The Wisconsin DNR asked the race to stop routing through the Emma Carlin trailhead starting in 2020, and the course has been adjusted since (a shooting-range-adjacent McMiller Sports Center section and an Eagle Horse Trail sandy section were both new as of the 2021 running).

Nobody sees it until we have read it. No account, no sign-in.

This changes nothing on the page on its own. Somebody checks it against the race first.
Seen a course preview or a film of this one? Send it over.
Somebody watches it before it goes anywhere near this page. What we are after is footage of this course, on the ground. If it would be just as true of any other race, it is not this.
Have the GPX? Send us the link.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
Are you the race director? Get in touch and we'll make it right.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
Where this came from.
Every fact on this page records its source and when we last checked it: 167 sources for this race. Hover a source link to read the sentence it came from.
37% of what we track for a course is filled in. The rest says "not checked yet" rather than guessing.
Ultras change. We will tell you when this one does.
Cutoffs move, races get postponed, lotteries open and close. We read the race's own sources and record where every fact came from. Put your email in and we will send you what changed, and where we read it.
No account, and nothing to cancel.
What happens to your email. Nothing else. I do not sell it, and I will not send you anything except this race changing. One click gets you out.
I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
