Friday is Bike To Work Day and more than 10,000 are expected to take part in the Washington area.
The Commuter Connections program run by the Metropolitan Washington Council of Governments says 58 Bike to Work Day pit stops will be open throughout the district, Maryland and Virginia.
The stops offer food, entertainment and prizes for cyclists. Organizers say commuters who bike to work help reduce traffic and pollution while also getting exercise.
Last year's event attracted nearly 11,000 bicyclists and organizers say this year looks to be even bigger.
Nicholas Ramfos, Commuter Connections Director of Alternative Commute Programs, appeared on ABC7's Good Morning Washington Friday to talk about the initiative.
