WASHINGTON, D.C. -- Across the country, tens of thousands are indoor cycling this weekend to raise money for rare cancer research. Some of those cyclists are in the District.

Each indoor team cycling event has to raise a minimum of $1,000, but an average of $5,000 per bike is usually raised. Teams consist of a captain and 4-8 riders.

They ride relay-style in four back-to-back fifty minute sessions. 100% of the money raised goes directly to cancer research.

The fight to beat cancer is a personal one for the founder of the campaign. In the video above, DCW's photojournalist Graham Knight explains how.
