The event takes place on 05/08/2027 at Cap Sauers Holding Nature Preserve in Palos Hills, Illinois, using the Sag Valley Trail system. The preserve covers the maintained Yellow, Green, Blue and Tan trails and is described as the largest tract of undeveloped land in Cook County, IL.
Distances:
- 26.2 Miles Marathon on Sag Valley Trail, 2 circuits plus 10k out-and-back.
