Were you able to get out and enjoy cycling today?

We had *balmy* temps today and I decided to go for it. The wind was calm and I wanted to do a lot of miles since we may have snow showers by Sunday. So I did 50 miles today. Did great until the last 10 miles and then my achilles tendon was screaming and I basically coasted back to the car. I was so mad at myself. I don't know what caused it but it sure kept me from finishing strong.
