The Speed Gamers are a group of awesome guys that run gaming marathons to try and raise money for charity. So far they've ran 8 marathons, generating a total of $15648.23. Right now, they're in hour two of a 72 hour gaming run through the Zelda series, attempting to clear 13 games by the end. All proceeds go to Ally's House, an Oklahoma based charity that supports children with cancer and their families. So if you've got a bit of time, please, give them some viewing love, and if you can, donate. And keep tabs on their site for future marathons.
