He has won a bunch of national championships--very fast guy at 57yo.
I used to be on a team with a guy in his mid 60s whose FTP was 4.3wkg. I'm in my mid 40s now and my FTP hasn't dropped from what it was in my mid 30s. Even the guy on our team in his 70s was very fast. Gives me a glimmer of hope that aging might not be as bad as I think it could be.
