My wife, two friends and I rode 75 miles on Saturday from South Charleston to Cincinnati, OH, mostly along the Little Miami Scenic Trail. It was the longest ride for any of us. One of my friends had little opportunity to train for it between the crummy "spring" here (we didn't really have one) and some kidney stones. He almost dropped out at the 62-mile mark but after a short break, he decided to continue onto the end with us, albeit at a lower speed.
We didn't hold a high average speed (we were just a tick over 14 mph) but it was great to set a personal distance mark for all of us. And dinner was terrific - it's amazing how good food can taste when you are famished.
On Sunday, after we all got home, I rewarded myself with a shorter session on the trainer in the basement.
