Anyone know a good one. My longest comfortable distance is 5 miles. Thinking of running a half in late April/early May. Anyone have a good training program or a good running app?

Hal Higdon has half marathon training plans for novice and intermediate runners:

Wow, I too am looking at running a half marathon (in May) and also run a 5 miles pretty comfortably. Right now I am working through p90x and then I plan to hopefully train for the race when I finish that.

I can't post links yet, but there is a training schedule on FitSugar that is pretty decent.

This is the one I've been using:
