While I'm not doing marathon-specific training yet (I'll start that in July), I do my everyday running schedule based on the marathon model. This one: http://www.marathontraining.com/marathon/m_sch_2.html

I keep repeating week 3, but with one less day off, and I keep pushing the Sunday run to 8-10 miles, depending on how much time I have.

Anybody else uses this type schedule? What worked for you?
