It's a gorgeous day outside, sunny and 33. I was supposed to ride with Hirakukibou this afternoon, but she had to cancel, so I decided to run instead. Not sure why, but my left hamstring started screaming. This always seems to happen after I've done a harder run on the treadmill. Perhaps I didn't stretch enough Wednesday or maybe it's all of the new yoga stuff I've been doing. I ended up doing a measly 2.2 miles and limping up my driveway. It feels better after doing a 10 minute stretching DVD segment and showering. Here's hoping it won't interfere with riding tomorrow.
