I've never used a canned program. If you just want to increase how long you can run, then pick a "long" run day and just increase how far you run on that day every week. In the middle of the week, change up the duration of your runs. Let's assume you run 4 days per week (like you did last January) then you might want to do something like this: M: T: 1x W: R: 2x F: 1x S: S: 3x If you want to run 5 days per week you could do something like this: M: T: 1x W: 2x R: 1x F: 2x S: S: 3x So basically, if your long run right now is 30 minutes, then your short runs are 10 minutes, medium are 20 minutes, long is 30 minutes. Next week, you might run 10/20/33. Week after that, maybe 10/20/37. Maybe in the 3rd week you'd run 10/22/40 minutes for Easy/Medium/Hard days. Every pace should be at an easy pace. Difficulty refers to time. Just a thought.
