Joined the ride in Boxboro, near Middle Street and Route 111. Rode by myself for about the first 4 miles, at about 13 or 14 mph to warm up, so that kept my average down. About 15 guys and girls, stopped at Harvard General Store to refuel, and continued up to Fruitlands and West Bare Hill, and Sugar Road. Stayed mostly with the front of the group, but struggled on the hills comparatively. Nice guys, they regrouped several times throughout the ride, much more than the Shifters or NVP would do. Clear, hot and humid but manageable temps. Hamstring still bothering me, so it's always hard to get up some of the hills, like Scott Road. Just noticed that it didn't fully record the ride going down Golden Run and the beginning of Sugar Road. Not sure why.
