Rockstar's New Yorkers are very passionite about cycling, and have presented the annual Harlem Skyscraper Cycling Classic for several years. This year, Rockstar is also presenting the Red Hook Criterium in Red Hook, Brooklyn - an unsanctioned, underground cycling series:

The Red Hook Crit, as it’s known, is a fixed gear bike race through the night streets of Red Hook, Brooklyn. Previously held twice a year, with Rockstar’s help the RHC is now expanding into a four-part championship series with races in select urban locations across the world. After the first round this Saturday, riders will again take to the BK streets for a new event at the Brooklyn Navy Yard this June. The series then moves to mainland Europe for the next stop in Barcelona in August before crowning its first ever World Champion in Milan in October.

Check out a little history on the series...

...including a warm-up video:

The 2013 series officially starts this Saturday night at 7:30 PM with men's and women's 5K runs, before the main event at 9:00 PM.
