New routes for 2025!  
Routes now going back through Hell, MI! (except for 19 paved and 22 gravel).   The short paved route (19 mile) a lot easier to follow!  Routes are: 19, 47, 64, and 100 mile paved; and 22, 46, and 68 gravel. 

All rides start and end at Chelsea Fairgrounds in Chelsea, Michigan. The roads will be marked and signs will be used to augment the road marks. 

Optional leader-led group rides led by an AABTS Member for the 22 mile gravel and 19 mile paved groups both leave at 10am. The 46 mile gravel and 47 mile paved groups both leave at 9am.  There will be signs at the Fairgrounds for each route.

Below are printable cue sheets and maps for the routes, as well as GPS files via RidewithGPS. We recommend you print and bring your route map and cue sheets if you want a hard copy. Limited printed maps will be available at registration. 

Routes and rest stops subject to change  - always check prior to the ride!
