I had to quit running when I was 50. I crushed my ankle in an accident. Fortunately, It does not limit bike riding. I'm also turning 79 years old in march, that also slows me down a little

Some of my times: 10 k- 00:33, marathon- 2:40, 50 k- 3:15, 50 miles- a hair under 7 hours. OK times, but nothing to get excited about.

Good luck with your venture. It really does not matter how you ride a bike, or what kind of bike you ride. It just matters to be on the bike, and riding.
