I seem to recall that you found this book in a jumble sale or charity shop a few months back?Thanks for the warning @Stuuuuuu. I will follow a plan nearer the time. I've got a marathon training book, and at the moment I'm trying to do around 40k per week. But I'm also trying to do some of the other suggested sessions like some core training, tempo, progressive runs, some hills (though I've not done the specific hill session yet with 10 repeats), and a few sprints.
This is what I'll be trying to follow from August.
