A screenshot of my Strava from Sunday's Golden State Race Series circuit race. This was the Masters 50+/60+ field, so by definition everyone in that race is eligible for AARP membership. I finished midpack, so this is a pretty representation of the race speed.
It's the same guys I've been racing against for years. I keep thinking that as I age up, racing will get easier. But no, those guys don't get any slower.
