The Nagoya Keirin Golden Dolphin Competition is a bicycle race—specifically a Japanese style track cycling event held in a velodrome—and this year's 62nd annual competition will be supporting areas affected by the 2011 earthquake. An anime clip was created as part of a promotional campaign, and you can see the cute, fictional Piststar "opening" in full below. 

The race takes place from March 24-27.
