i'm almost over 50 and i just recently started riding - my husband is an avid runner and biker. he's been trying to get me on a bike for awhile. he just bought me a new road bike - what a difference from my hybrid! i'm so impressed that i'm actually going to buy some biking shorts and a shirt (gotta have the right equipment).
i'm a little on the chuncky side (hence the big guy's efforts to get me out on the road) and was excited to see plus size apparall.
i can do 20-25 miles fairly well if there aren't a lot of hills. an over 40 ride would be fun.
