Fifth Third Riverbank Run training log

Speaking of schedules, I just looked at my March training schedule (running). Its crazy! I am following a beginner's schedule. So my schedule for March 1 is: walk 45 min. (yeah, easy!); March 2, run 3 miles (?); March 3, run 4 miles (??); March 4, run 8 miles; March 5, off or 2-3 miles. This is a beginner schedule?? That could amount to 17-18 miles in a row. I am trying to keep my foot from giving me fits, and yet I am supposed to be running anywhere up to 18 miles in 4 days' time? I really need to think this one through a little better. I would actually love to run that many miles in a row. I used to easily run that many miles a week and more, and now am freaked out by that much at one time.

I know I use triathlon training as a way out, and its not really a way out, but at the same time I am not really planning on too many running events, much as I would like to. I really need to rethink this.
