I've decided to take a few weeks from the marathon training plan that I used. I'm going to start with Week 4 - runs of 3, 4 and 3 miles and a 9 miler on the weekend. Starting next week I may use the mid-week longer run as a speedwork run - I'm going to give myself a break this week as I haven't really run much in two weeks. I may also do some hill sprints after one of the weekly runs as well.
It will be good to have a training plan to follow once again.
