North American-based companies will spend an estimated $86.1 million to sponsor marathons, triathlons, 10Ks and other running events this year, a 2.5% increase from the $84 million spent in '08, according to IEG, a sponsorship research and consulting firm.

While the projection is down significantly from the nearly 9% increase in spending from '07 to '08, it outpaces IEG's expected 0.7% spending increase on overall sponsorship of sports properties.

The reason: Increasingly sophisticated sponsorship sales techniques by marathons and other types of running events, as well as the upscale demographic of runners and other endurance sports athletes.

“Corporate marketers continue to be enthralled by endurance sports' affluent participant base,” said William Chipps, senior editor of IEG Sponsorship Report.

Corporate interest also has been fueled by a new player on the scene: Competitor Group Inc. New York City-based private equity firm Falconhead Capital, LLC formed CGI in January '08 following its acquisition of four media and event companies in the endurance sports space: Competitor Publishing, Elite Racing, Triathlete Magazine and Inside Communications.

The acquisitions gave CGI a number of assets – including the Rock 'n' Roll Marathon Series, the Muddy Buddy Series, Inside Triathlon and Velo News – around which it is offering multi-dimensional marketing platforms.

Those packages have caught the interest of corporate marketers, with CGI this year securing new deals with Brooks Sports, Inc.; Nissan North America, Inc.; Amway Corp.'s Nutrilte vitamins; and MillerCoors, LLC's MGD64 brand.

Other new deals in '09 include The Procter & Gamble Co., which inked presenting status of the Cincinnati Flying Pig Marathon, and the Jamaica Tourist Board, which partnered with the Nautica New York City Triathlon. Manhattan's Hospital for Special Surgery and T-Mobile USA, Inc. both signed new deals with the ING New York City Marathon.
