About The Longest Day (100k - 50k - 26.2 - 13.1)
The Longest Day
Sun up to sundown. Who can last? ☀️
A two-mile grass loop through 120 acres of forest and open field, run under a cutoff that gets one minute shorter every single lap. Forty-five minutes for the first. Fifteen for the thirty-first. Seven laps is a half marathon, fourteen is a marathon, sixteen is a 50K, twenty-five is fifty miles, and thirty-one is 100K. The clock decides when you are done, not you.
The format is what makes this race. Early laps feel generous — 45 minutes for two miles is a walk in the park, and it very nearly is one. But the window closes a minute at a time, and somewhere in the afternoon the math stops being theoretical and starts being the only thing you can think about. Miss a cutoff and it is over: ring the cowbell, turn in your bib, and go cheer for whoever is still out there.
The course itself is grass trails with rolling hills, open fields, and sections of shade, winding among red cedar and maple through the preserve. You may see white-tailed deer, a box turtle, or a fox. Note that there is NO WATER OR POWER ON SITE, so plan your crew setup accordingly. Bring a tent, a camp chair, and your support crew — Friday evening setup begins at 5:00 PM and overnight camping is available.

Course

Lap Cutoffs
