The doctor wants me to stress the hamstring by running faster. So last night, I hopped on the treadmill for 8 quarter mile repeats. Last week was the first time I'd tried anything remotely resembling speedwork since April, so I took it really easy - six quarters at 8:00 mpm pace. Those repeats felt pretty easy, so I sped up to 7:30 pace this week for 8 repeats. On the last one, I sped up to a 7:00 pace.
Overall, the hamstring felt pretty good. My stride still isn't quite right, but my left leg is extending better week by week. I think that is part of why the doc wants me to push the pace. As I run faster, my stride at slower speeds seems to be getting better and better.
But, racing a 5K on Saturday is just plain going to hurt, because I'll do it all out, with no real running base or speed right now.
Tonight is my "100 squats" workout, so my legs will really be beat tomorrow.
