Part food drive, part shopping cart race and part street-side spectacle, the seventh annual Chiditarod (pronounced shy-DIT-a-rod) aims to collect more than 10 tons of food by the end of the day. Teams of five propel shopping carts like dog sleds, with four "dogs" pulling ropes in front and a musher steering from the back as they try to find the quickest way to get from the start to the finish line, collecting food en route. Food items can be stuffed in pockets, delivered by friends to checkpoints or hidden along the route. Contenders must have 42 pounds of food at the finish line. Prizes are awarded for top finishers and most food collected. Costumes and decorated carts are encouraged.
