The Fancy Nonsense 25k/50k is designed to test your mental and physical limits and to tickle your funny bone. It will be run on single-track trails located in the Palos Trail system just southwest of Chicago. There will be some elevation. There won’t be any werewolves, we didn’t invite them this time.(Or did we?) You can count on three aid stations split evenly between the double out and back. One at the start one at the turnaround and one plopped right in between. You'll pass by the buried remains of Chicago Pile-1, the world's first nuclear reactor.
