What an experience. Spent the afternoon riding trails in southern Wisconsin. The John Muir and Emma Carllin trails. Had no idea what to expect, and man was it challenging, intense riding. Even more of a challenge using vintage steel outfitted with cyclocross tubulars and just a basic bike boom bike.

i pretty much stayed in my 42/28 low gear the entire way. Dismounted for insane grades and big rocks, fallen trees etc. Took 2 hours to complete an eight mile loop. Walked a few sections, stopped to catch my breath. Had one fall but it was at super slow speed. Kinda crazy, but exhilarating, and a great workout.
