HOUSTON -

Clad in brightly-colored jerseys, seven convoys of bicyclists from some of the world's top energy firms commuted into work at dawn Thursday for the 10th Annual Energy Corridor Bike to Work Day.

Sponsored by The Energy Corridor District, Bike to Work Day is designed to promote cycling as a fun and effective alternative commute.

"It's one way to combine exercise [with] a commuting option," said cyclist Bryan Gorrell.  "Another way is to reduce your carbon footprint, and also to raise awareness about alternative transportation."

Convoys started from the historic Heights Fire Station near 12th Street and Yale Street and made their way through town to the Terry Hershey Park gazebo.

After the ride, participants enjoyed a free breakfast, raffle prizes, giveaways, bike maintenance stations, and more.
