Race organizers for the North Carolina Marathon in Greensboro are making a very conscious effort to go green next year, according to this recent article. From more recycling to email-only communication, it definitely looks like they are doing their best to stay on top of greening efforts.

The article also talked about interesting changes at other races-- from bamboo shirts handed out at the Portland Marathon to the 2,000-gallon water fountain at the ING Hartford Marathon that eliminated the need for 10,000 plastic bottles.

What do you guys think about all this? Do you have any other ideas on ways directors can green their races?
