A competitor runs during the Idiotarod race in Brooklyn.

Organizers of the Brooklyn race, now in its 10th year, called the cease-and-desist letter frivolous, but agreed to rename the event the Idiotarodorama (aka the Desistarod).

Still, race organizers insist that the Idiotarod, described as an "urban spoof" of the famed dog sled race,  could never be confused with the Alaskan event.
