I just doubled my longest ride of the year! I went out planning on doing a 20 mile bike ride on my road bike, but found a riding group. Before I knew it, I had cranked in 40 miles with them. I said what the heck, and put in another 8. So, I guess I should correct myself. I only did 48.38 miles, but I did average 17.66 miles per hour.
(my furthest ride ever was back in September when I did 63 during an attempt at a century. I think I am on track to be able to finish the century this year.)
