Running? More like walking

Good Morning and welcome to the new day!

For some reason late last year, I thought it would be a good idea to set a goal for myself. So, I thought, wouldn't it be great to train for the Broad Street Run?
I have never done anything like it. I was told by some I would never be able to do it. Of course, that meant I was going to do it come hell or high water.
So, the run (I won't call it a race, because I'm not racing) is Sunday. I have a week left and, as it turns out, a weak right leg.
I was so resolute in my training, I fear I may have overdone it. Last week, I started to get cramps in my calves.
It all came to a head Saturday night when I used the Haverford Twilight 5K as my final training run. Well, OK, it was a training walk. About a mile in, the pain in my legs started. I wasn't going to stop, though, and I still finished in 40 minutes (what I was really shooting for).
Of course, when the 90-year old with the walker passed me on the course, I thought I might be in trouble.
So, I'll use ice, I'll eat a lot of bananas (saw on the Internet) and I'll be ready Sunday.
Well, that's the plan anyway.
