The Challenged Athletes Foundation (CAF) believes that involvement in sports at any level increases self-esteem, encourages independence and enhances quality of life. On this week's QuadCast, CAF Senior Director, Doug Olson, and 6x Ironman finisher, Glenn Hartrick are my guests. Doug explains what CAF is, and how they help the physically challenged participate in sports, and Glenn tells us what competing in a triathlon is like, before and after a spinal cord injury.
