PHOENIX - Hundreds of workers are ditching their cars and biking to work Wednesday morning as part of an effort to help the environment and also exercise.

At the Park Central Mall near Thomas and Central avenues, bicyclists registered, grabbed T-shirts, hopped on their bikes and headed to Cityscape.

The three-mile jaunt is because of National Bike to Work Day. For the rest of the nation, the day is always the third Friday of May. (May 19, 2017 will be the day for this year.)

Since the temperatures in Arizona get extremely hot, the day is celebrated a month early.
