Help, please

Ok, I'm going to stray from my typical blog topic to ask for help. I am trying to grow my hair out. I cut it very short just because I wanted to try it and while most people love it, I'd like to grow it out.

Fixed, it looks like this:

I'm the dark headed one :)

My problem is that when I run and it's not fixed, it looks like this:

bleh!!!

So I'm wanting to grow it back out. I just don't know what hairstyle to go for. Can y'all recommend anyone??

I have think, curly hair..
