This week since the AM rides are out I rode with a group from work that goes out at lunch. I rode Tuesday with them - 20 miles of rolling hills - 19.8mph average. That was tough. Thursday I tried again, it was a cooler day so I wore a jacket. This days group was even faster. When they cranked it up to 28mph I was burning up in the jacket - after about 7 miles I was spit out the back, they pulled up and said they were going to do 30 that day - I waved "bye bye" and cut it short to 15. Maybe I'll try again next week.
