Ran the Warrior Dash today, and by pure luck, I managed not to maim or kill myself.
The nature of the event (obstacles, mud, water, barbed wire, junkyard metal, etc) makes it a perfect opportunity to "retire" a pair of running shoes, but all is not lost, because even though they might be ruined for the purpose of running, there's still a lot of practical use remaining. One of the cooler aspects of the event is participation in the Green Sneakers program, which aims to bring these shoes back from the brink of destruction, clean them up, and distribute them to people around the world.
Among the photos I took today was this shot of one small section of the mountains of piled up used shoes:
Part of the donation process involved tying your old shoes together so that they didn't get lost, so each shoe has a sibling not too far away.
There's a .zip with pre-sized desktop wallpaper images, covering a large range of screen sizes, located here. Enjoy!
