Chicago Marathon outdoor - talk about a cool experience. On 10/10/10, I ran my first marathon (read about it here!). It was a killer day—85 degrees over 26.2 miles. It was tough to keep going, but every so often I'd pass a bus shelter with one of these posters. It made me proud and gave me that little kick of motivation I needed. And feel free to check out the photos from my marathon weekend on Flickr.
