In my 60th year, I set three goals for the year. My birthday is in winter and it did not occur to me to do a ride in snow and ice. I think 60 is a big one.
I wanted to 1) complete Paris Brest Paris 2) Break 20 minutes for 10 miles 3) Do a sub 4 hour 100 mile ride solo.
Due to health issues, I never got around to 100 miler but did do a training ride of 100Km in 2:30 on less than good conditions
