Really nice day, finally not too humid. After four hours of tennis on Friday I woke up very sore in my back, and my right knee hurt, but one tylenol helped. I felt overall pretty good, and could keep up with the group at the front, even on the hills, despite my butt hurting a little. My saddle was ok, I think these shorts are better than my other shorts. Going up hills after mile 20 or so I noticed that the gears were not shifting very efficiently, and then at top of Sawyer Hill, my shift lever for the rear derailleur stopped working. I couldn't shift and the chain was stuck in the highest gear. After fiddling with it a little at the coffee stop, tried going up hill a little but had to walk and a guy named Chris helped me by adjusting the set screw in the rear derailleur, which got me to the fourth gear so I was able to power up the hills ok in the end, but it was mostly downhill after Warner Road. So my average should have been a little better than it was. Amazingly, according to my Garmin I was riding mostly in the warmup and easy range, which is very strange. Also, very nice route, some of my favorite hills including Long Hill, Century Mill road and Peach Hill, where we saw a view of Boston.
