20-mile run!

Well, I was able to knock out most of a 20-mile run on Saturday. This one was in the Anthony Chabot Regional Park also with the LMJS marathon training group. It had a few hills which after 10 or 15 miles were tough. I had a mild strain in my right calf, so I walked the steeper hills after about 10 mile mark. A also ran out of gas at about the 17-mile mark and walked for a bit then as well. I've been slow to incorporate eating into my runs and I now see the error of my ways! After eating 1/4 of a sandwich I felt better and was able to finish the run.
This coming weekend is a 22-mile training run. This will be my longest run in preparation for the full Marathon on July 29th. I'll try eating a small amount every hour of this 4-hr training run and I'm hoping this will improve how I feel later in the run. In the meantime rest, ice and Advil as I try quickly heal this minor strain in my calf...
