Under Armour, which has been the title sponsor of the Baltimore Running Festival for the past 10 years, will not sponsor this year's race, which will be held Oct. 12. The race is seeking a new title sponsor, Corrigan Sports Enterprises announced Saturday.
Under Armour still will be involved as the event's official apparel provider and furnish every participant with the company's moisture-wicking performance shirts.
Under Armour has spent millions on the race over 10 years. Last year, the company paid about $500,000 as the main sponsor.
Lee Corrigan, whose company operates the marathon, told Baltimore CBS news that Baltimore-based Under Armour decided to spend its money in the community in a different way. Last fall, Under Armour donated funds to Dunbar High School for a new athletic field.
