Foursquare Founders, Usain Bolt Team Up For NYC Marathon

By: Sara Yin

Jamaican sprinter Usain Bolt is running alongside Foursquare co-founders Dennis Crowley and Naveen Selvadurai at the ING New York City Marathon this Sunday in an effort to raise money for a children's charity, and marathon participants can help with that effort via Foursquare.

The selected charity, Camp Interactive, is a non-profit organization serving underprivileged kids in the Bronx. It takes them on outdoor expeditions and teaches the kids how to use social media to document their experiences online.
