My shins started playing up today after only 5 minutes of running. It's a long time since I had any problems with them. The gym was still unbearably hot and the huge fan did little to reduce my dehydration. I'm supposed to run 3 miles tomorrow and then 6 on Saturday. I think I'll attempt a few more than 3 miles tomorrow to make up for the poor runs I've had recently. Maybe if I get plenty of rest beforehand and stretch out my legs a bit more I'll be able to have a fairly uneventful run for once.
