<human>: Summarize the given text in a few sentences.

I never thought I would be one of these posters - I usually plan things out pretty far in advance and train - but here I am, contemplating signing up for a half marathon that occurs 10 days from now.

The background is this: I ran a half in fall 2012 and it was pretty disastrous - over 2.5 hours. A few months later, I was diagnosed with severe anemia, which explained why throughout my training I was getting slower (my husband just thought I was being lazy, but it turned out I had no iron!). 

Fast-forward to now. I've been taking my iron pills and eating lots of oysters like a good girl, and my energy level is back up. I hadn't been running much this year because I moved to a not-very-running-friendly country last summer, but for the past two months I've just said fuck it and started running anyways. Since I'm not really training for anything the longest I've run this time is 10K, but I'm running almost every day and feeling good.

Rationally speaking, I should just do the 10K event on the same day, but races are so few and far between in my country and I feel like I could probably beat my previous half even without the training... but am I being crazy? If I do decide to do it, how do I approach the next 10 days - should I try and do another long run between now and then, or just stick to short ones to keep my legs loose?
