I am 66 years old (Male) and started to train on a road bike in December. Spent the winter in Gulf Shores Alabama (snowbird) and trained 5 days a week and worked myself and my girlfriend up to 175 miles per week in the end (March 5th) before we left, avg 14 mph!

My question is, are we overdoing it? And, is 5x a week too much? I plan on resuming training here in Michigan once the weather gets decent! P.S. Nothing like falling in love with biking, I'm addicted now!
