From the TCBA website:
…Riders will have choices of the traditional route distances of 25K (~17 miles), 50K (~34 miles), 100K (~65 miles), and a 45K (~30 miles) gravel road loop with a new Tough Biker trail loop option. Routes use rural western Eaton County roads. Riders who choose the 100K or the 45K gravel road ride will also venture into eastern Barry and southern Ionia and Clinton Counties. Riders on the 100K route will pass through Vermontville, Woodland and Lake Odessa.
Lunch will be served at the school [and] all routes will pass through at least one rest stop with volunteers serving assorted fruits, freshly baked cookies, and beverages.
In order to get in the full metric century before noon, the plan is to ROLL AT 8AM.
Registration is $17 for adults. This ride $ qualifies for a credit at the end of the season through TNR if you complete your charity obligations.
