Earlier in the week I ran half mile intervals. I ran them at 6AM. Although it was very hot and very humid my paces were right in line. I gave myself some leeway but I was a bit faster. There is a fine line between blowing up and hitting your marks. Since I was only running 4 x 1/2 mile with 90 seconds rest I felt comfortable in pushing the pace. If I were doing 8 or 10 of these intervals then I would have backed off about 5 seconds. So I was finished all of them in under 3:03. This is a few seconds slower than the winter intervals but I will take it!
There was another purpose of this run. I ran in my race shoes without socks. There are the same shoes that gave me blisters a couple of weeks ago. I did not wear them during the Heat Wave because of this. Preparing the race shoes.
This time while running the intervals I did not experience any discomfort. There were no hot spots. I just felt fast. After the session I did notice that I had one blister on my right foot. It was nothing major. That was few days ago. I am confident that I will be able to wear these race shoes for the Dragonfly. Progressive overload works for just about everything. Create a stress and let it recover. It comes back bigger and stronger. That works with training and preparing summer feet!
