50 mile training

I am signed up for a 50 mile run on October 10. If I was to follow directions, here is an example of what a training schedule should look like. The x means tempo (I never do formal tempo runs). Where is says, PR, that is where I am signed up to run the Patriots Run, a 9 hour and 11 minute run. I may have to adjust the weekend before to account for this. I am going to try to follow this plan somewhat to ensure I don't over-do things.

This week, I ran 64 miles plus about 6 hours of walking.

This morning, I had a beautiful 13 mile run in cool temps and bright sunshine. I said to myself, if today was my last day on earth, I think this is where I'd like to spend it and what I'd like to be doing.
