I got in 20 miles. First day that I rode in over 80 degree weather. I found a hill so steep that I was afraid to look at my spedometer! I KNOW what 25 mph feels like and it was faster than that. On the return trip, I almost made it up the hill. I got nervous, unclipped and lost my momentum. All with only 50 yards to go! The rest was fun and more hilly than usual for me. I live in a pretty flat land so any hills are a challenge. I am just starting to get the hang of when to change and which chainring to be on.
