Just a reminder: Some streets of T.O. will be filled with bicyclists on Sun., May 23 because Thousand Oaks, Westlake Village and Agoura Hills are hosting the Amgen Tour of California.

Patterned after the Tour de France, the Amgen Tour of California is the largest professional bicycle race the United States. The weeklong race will finish in Thousand Oaks.

Top-name cyclists expected to participate include seven-time Tour de France winner Lance Armstrong, three-time Amgen Tour winner Levi Leipheimer and David Zabriskie, who placed second in the Amgen Tour last year.

City spokesperson Andrew Powers said he expects the event to be economically helpful to Thousand Oaks, with an expected 100,000 to 200,000 visitors coming to see the race.

For those not excited about bicycle racing, Sunday might be a good day to take a trip out of town.
