Alley Cats are a form of bicycle races meant to simulate the daily trials of a bicycle messenger. The contestants are given a manifest of pickup and dropoff points and must decide the quickest route and deliver the items in the fastest time possible.
For this particular (Thanksgiving-themed) race, we were given a list of several different grocery stores throughout Los Angeles in which to pick up items for a food drive.
Big thanks to Venice Chill Ride for hosting the race, Daniel Lee for letting me borrow his GoPro, and Daniel Alvarado for dragging me out to this and recording extra footage on his iPhone (He's the guy you see the most in the video).
The song is We Are Your Friends by J.U.S.T.I.C.E. vs. Simian

Flip HD attached with electrical tape to the back of my bike
Then an HTC Incredible and iPhone 3GS when both of those ran out of batteries
