Last night was my beer softball league, and for the first time in a while, I decided to tie one on. It left me feeling not 100% today, but I still managed to take a few turns in the park behind our house and get in three miles. I then had a double-header with my other softball team tonight. The combination of being tired from last night, already having a few miles under my belt, the super cold temperatures at night, and a few quick sprints around the bases gave me a twinge in my left calf tonight. I'm hoping it's nothing, just a tweak, a little overuse... we'll see how it goes in the next couple of days. It's funny... when I first started feeling it, my first thought was, "wonder how this will affect my running schedule... will I still be able to go for my run tomorrow?"
