I'll be riding in my eighties even if it has to be an adult tricycle :)
A well-known local cyclist in his 90s once stopped to see if I needed help when I was adjusting my seat. He pointed out his house and said to stop in anytime if I needed bike assistance or tools. He rode in masters races in Florida and collected lots of medals. He was surprised and touched that I recognized him but he'd been on the cover of the local paper with all his hardware! So cool. Sadly, he is no longer with us.
CX on an adult tricycle....we will have to work on getting that category established.
WOW! Sorry for your loss and what an inspiration!
