CMAR Trail Races: Cry Me A River
CMAR Trail Races is a multi-distance trail running weekend held at Camp Wokanda near Chillicothe, Illinois, on the Illinois River Bluff Trail. The event uses a loop format on river bluff and camp trails and includes camping over the weekend. Terrain features wooded ridges, rolling hills and repeated climbs with significant elevation gain; July heat is noted as a factor.
Course details vary by distance. Routes use a short lodge loop plus out-and-back sections to aid stations such as Green Valley and Moose Shelter. Notable elevation figures and cutoffs are published for each distance:
- Half marathon: total elevation gain about 2,815 feet with a 10 hour cutoff.
- 50K: nearly 6,500 feet elevation gain with a 15 hour cutoff.
- 50 mile: two 25 mile loops with nearly 9,300 feet elevation gain and a 22 hour cutoff.
- 100 mile: four 25 mile loops with about 18,500 feet elevation gain, a 36 hour cutoff, and pacers allowed after two loops.
- 4 mile fun run: a two lake loop from The Lodge.
