I'm 52 years old ... from on VeloViewer, since I started tracking rides with Strava, I'm riding 4,000 to 6,500 miles per year.
And because Minnesota is flat (hard to find a climb over 100ft), my annual elevation gain is 100,00 to 250,000 feet. My old commuting route was rolling and really added up the elevation, but I work a home-office these days and can wimp-out for a rail-trail day when I don't feel like climbing.
And to keep the 'post a Bianchi pic' trend alive ... My Infinito at the summit if
