Another glorious day on one of my favorite rides. Wanted to do a second day of riding in preparation for the PMC. After yesterday’s hard ride, this was going to be an endurance ride. Legs were sore, so there were going to be no hard efforts going up hills; just tried to spin and get the legs working. Was feeling a little better in the second half. Decided to call an audible and extend the original 52 mile course to take in Great Brook, Greenough, and River/Monument, which is always nice...except for the scarified road for 2 miles as Concord does road work. Tagged onto a group of 6 riders at North Bridge and road to the top of Strawberry Hill. Was close to getting a metric, so did 3 miles on the Bruce Freeman Rail Trail to get the full distance. Such slavish devotion to arbitrary goals. Tired but glad I got the distance in on such a beautiful day.
