I love participating in races. I love the training (well, most of the time), I love the adrenaline, I love the camaraderie. Probably I'd love winning, if I ever did, but as it is, I just love being a part of the event. However, I don't love the impact these events generally have on the environment.

Think about it -- races create a large amount of trash (paper cups, water bottles), cause large numbers of people to travel, and what do you do with all that swag? Maybe you keep it and use it, but lots of people just throw it away. Races can be really wasteful.

Fortunately, they don't have to be. Event organizers have a couple of options if they're hoping to "greenify" their event. Both Athletes for a Fit Planet and the Council for Responsible Sport have several ways to help organizers make their races more environmentally responsible, plus they provide information to athletes who want to make informed choices about their races.
