I drove to Rochester and did a short ride from the Clinton River Trail to get to the Brewery then set out using my Wahoo and a turn-by-turn navigation from a GPX one of the bike shop guys gave me. Worked perfectly. It started pouring in Rochester, but it subsided after a little while. Once I got passed Stony Creek High School, it was almost all dirt and gravel roads. Michigan is very rural in places, as rural as some of the really rural places in Maine. This is my longest ride so far. I had an absolute blast, though I will likely be a bit sore in the morning. Beautiful area once you get out of the suburban mess. I will likely start doing the Thursday evening rides with the slower group from the bike shop. They ride about what I did today. Will likely work into it and try to keep up with the first group in the fall.
