3rd Annual Elysian Park 5k Eco run, Los Angeles

There will be countless footprints left on the 3rd Annual Elysian Park 5k Eco Run's cross-country course. A major carbon footprint won't be among them, though. Green Running Events, the people behind the run, strive to organize sustainable events. For example, they arrange car pools and opt for digital goody bags instead of the tangible, money-filled duffle bags of yesteryear.
