I will be 60 next year and dont intend to give up cycling. A forum for 50+ is an excellent idea. I have learnt much from Joe Freils book especially on endurence and speed. After 2 angioplasties I can definitely say my cycling has improved. Cant beat my 24 yr old son but I am close behind him.
I only have problems seeing near without glasses, so going downhill on my mtb is not a problem but reading maps is. Maybe I'll start a 60+ forum next year.
