In the spirit of adventure the Panaracer Psycho Killer 100 will be unmarked! We will provide GPX files, cue sheets and maps for you to navigate the course. Confirmation mats will be there to keep folks honest. The only exceptions will be turns without road signs. All of the info will be available on our website well in advance! #gravelgrinder #gravelroadrace #barryroubaix #10thanniversary #psychokiller100
