3 Rivers Bicycle Coalition is challenging people to bike to work this month.
The coalition is working with local bicycle retailers on the Bike-to-Work Challenge.
Bicyclists can pre-register at Scott's Cycle & Sports, Kennewick Cycle & Fitness, REI, Greenies, Markee's Cycling Center and Chain Reaction.
Those who participate will keep track of mileage and the number of days they participated and turn them in for prizes. There will be prizes for most miles and most days for women, men and teams of up to five cyclists.
