On the Fence

If you've seen my last couple of posts, you've seen that I'm trying to start running a bit more. 

Recently, however, I've been considering the idea of joining Team in Training this fall to train for either a marathon or half-marathon and to raise money for The Leukemia & Lymphoma Society. I'm excited about the idea, but also a little nervous - the longest that I've ever run is 6.2 miles (nowhere close to 13.1 or 26.2) and I've never tried to raise that much money before, either. So, it would definitely be two big firsts for me. 

So, any ideas for me? What would you do?
