Today I did my first 100 mile ride...in my third year of riding real road bikes.
Weather was perfect. Completed in a little over 6 hours...I have come a long way from where I was a few years ago, when such a feat would have been unthinkable.
I felt pretty good most of the day except that with about 15 miles to go my feet started hurting...which is never a problem for me on my typical 50 mile rides.
