Here's my life running story:

Before this year, I had never in my life ran for a mile without stopping to walk.

This January I went on a long-ish bike ride (15-20mi) every weekend, just for the hell of it. Well...okay fine, it was actually because my new years resolution was to "Be more active". Anyways, I enjoyed being outside (believe it or not!) and being active. I noticed a significant improvement in my stamina over just those 4 rides so I thought I would try running again.

I began running in February of this year, doing it 2-3x a week. I started out at 1.5-2mi, but still had to stop to rest.

I first ran 3mi without stopping on Feb 22 (10:00/mi).

Last Sunday, I ran 5.1mi without stopping (9:00/mi). 

This is starting to get addicting because it feels great being outside, and it's fun tracking yourself as you improve (I'm using MapMyRun).

Today, I learned about the Chicago half-marathon which is on September 9 (5 months away).

Do you think I can get to half-marathon distance by that time? I can probably make it out 2x, maybe 3x a week until school ends in June, then I can run as much as I want (At least...I think my summer job won't be too demanding). The reason I'm asking here is because I don't have any experience with long-distance running and don't *really* know how difficult training for this will be, or what obstacles I could potentially face on the way to 13.1.
