71 (today) here and am going to try the strava this coming season (mainly so I know the feet of climbs vs guessing) I have an edge here as the designer of the website my club has is a geek and has already explained much of what I need to know about using this. I did some respectable times on the road race courses last season and just may try cat 5 (first time competing in 30 years)next season. Here's my view..the older we get the less competition in our age group. "outlast the competition"!
