Hey, I can join this one now too -- turned 50 in April. Feeling very good and fit (and I won't even say "for my age")! Running 3x a week (3.5 miles each time), and riding my bike nearly daily now that I'm retired in Belize. Most rides are short (7-9 miles) commutes to/from town for groceries in 4-6 stops daily at all the little stores and fruit stands, so nothing like the long rides I used to do in NC but fun nonetheless. Living car free down here, so my bike is my transportation! :D
