Even though it conflicts a bit with the Jack Daniels plan I'm trying to follow (which has me running 7 days a week, about the same mileage every day during the first phase of training), I found this video by Jason Fitzgerald on planning weekly mileage to be useful as I try to put together a marathon training plan.

I like this guy's writing. I'm currently planning my summer marathon training and came across this article. The entries after this one mention him getting sick and DNFing his race -- but I'm still probably going to switch to 7 days a week of running as I increase my mileage.
