MINNEAPOLIS -- Training for the Olympic Games is more than a full-time focus for most athletes.

For Caitlin and Brian Gregg, qualifying for the US cross-country ski team is a track they've been on for years. But that's just one part of their mission in life.

The couple volunteer regularly at the Boys and Girls Club in Minneapolis, where they have set up a run club. Children show up as often as they want and run distances for prizes or healthy treats - like organic apples. They hope to help children learn healthy habits to be successful in life.
