Calera Capital has won the auction for Competitor Group Inc., the sporting event and media company that operates Rock ’n’ Roll Marathon.

Terms of the deal were not disclosed.

Competitor Group, based in San Diego, was established in late 2007 by Falconhead Capital when the firm merged three portfolio companies: Elite Racing Inc., La Jolla Holding Group LLC and Competitor Publishing Inc. In February 2008, Falconhead purchased Boulder, Colo.-based Inside Communications Inc., a publishing company geared toward competitive cycling and endurance sports, for an undisclosed price.

Competitor has since gone on to operate a total of 83 events across the world including the TriRock Triathlon Series in seven markets and the Muddy Buddy series in eight markets. It also owns five publishing properties including Velo, Inside Triathlon, Triathlete, Competitor Magazine and Women’s Running.

The company has grown about 40 percent per annum, according to Falconhead chairman and CEO David Moross.

New York-based Falconhead hired advisory Perella Weinberg Partners LP in June to run the auction.

Calera is headquartered in San Francisco.
