You are an inspiration with some very good wisdom.
In my early 30s I was a pretty decent climber and could beat almost all the other club riders to the top. Was always in the top three. In my 40s went out with a group from a LBS with all ages. Paceline ran at an insane 25 for 7 miles. Then we got to the climb. That’s when the kids in their late teens and early twenties just blew the pack, including me who had been holding on for dear life, apart. That was reality's hard slap across the face. No longer young, no longer competitive. I will never forget that day. Except today when I ran out of breath.
