Good information. Thanks. I took it easy this morning. Will take it easy for the rest of the week. Funny, last week I only got two rides in due to weather and family responsibilities. Rode 45 that Sunday and had numerous 20+ mph splits (fast for me). Felt great and felt like i could have done it again when I got home.

My goal is just fitness and avoiding the stress of driving. I don't race. I usually ride alone.
