In past posts, I've mentioned that my left foot felt "weak" after long runs. That condition is getting worse. The "weak" feeling starts at about 8 miles, and by 10 miles, my foot is starting to feel sore. As soon as I stop running, the pain stops. Right now, it has been about three hours since I finished my two-hour run, and my foot feels fine.
I don't think my foot is injured, because the "weak" feeling is like the feeling I used to have in my feet after several hours of yard work. In fact, that "weak" feeling and soreness was the reason I started running. I think the problem is due to the fact that it has only been a year and a quarter since I went past 10 miles and on to 15 and then back to 13 miles. During that time, I've done a lot of fast runs and speed training. I think my body just needs more time to build strength.
I am concerned about the half-marathon on April 21, because if my two-hour runs last week and today are indicators, I would have a hard time finishing the race. I'm going to wear an Ace bandage on my foot for the long runs between now and the race (including the race). After the race, I will need a month for recovery, and during that time I will just run comfortable runs with no speed work. Then I'll just have to run the summer and fall by "ear" so to speak.
