As for training plans, I'm more than likely going with the FIRST program. I like the concept of focusing on three quality workouts a week (speed, tempo, long) and supplementing the off days with cross training. Of course, every training plan depends on how well you stick with it and seeing it through to completion has always been an issue that I've had. After running eleven marathons, I haven't PRed since marathon # 2, the last time I followed a training plan faithfully. Hopefully the flexibility of the FIRST plan and the fact that it's only a 16 week program as opposed to 18+ will keep me on track.
