I am trying to decide whether to do a half marathon in late April. Obviously I will ultimately listen to my body, but just wanted thoughts on whether you would do it...

Background:

1. I have run all distances (5k to marathon) the past three years, and generally consider myself half marathon ready within a few weeks notice.
2. I took it really easy after my last marathon in Nov and didn't run longer than 6 miles from Nov to Jan.
3. I had to take a month off running due to spotting and am starting back Friday.

I would be nearly 18 weeks at the time of half. Thoughts? Is that unreasonable to train for?
