Blisters with 6 days until the marathon :(

    Well I ran a great 6 miles on Monday 9/5 then started to feel like I am getting a cold. I took off the rest of the week. Feeling a little better, I decided to do 90 minutes of walk/ running on Sunday. A little over an hour in, I began to feel like I was getting blisters on the back of both feet. Same socks, same sneakers that I always wear so I don't know why. Maybe because I was walking part of the way. Of course, I forgot my cell phone, so I took my shoes off and walked the 2 miles home. It was horrible. Now the bottom of my feet hurt as well. Not sure what I will run this week. Marathon in 6 days!!
