The company has signed a multi-year deal with Corrigan Sports Enterprises Inc., which organizes the running festival, to be the official race-themed apparel and footwear provider.
That includes the performance shirts that participants in each of the running festival's events -- the marathon, half-marathon, 5K, relay and kids run run -- receive as part of their official race package. Race participants have received Under Armour shirts since 2003. This year's race is scheduled for Oct. 12.
Corrigan Sports President Lee Corrigan said in a statement that Under Armour's involvement had "strongly contributed to the global interest in Charm City’s premier running event."
"Runners treasure our race shirts, and because of our decade-long partnership with Under Armour we’ve been fortunate to provide our athletes with the best shirt in the industry," Corrigan said.
Corrigan announced in August that Under Armour would not be the race's title sponsor this year. A spokeswoman for Corrigan Sports said a new title sponsor is still being sought.
Under Armour executives said they pulled their title sponsorship so that they could spend their money on other sports projects in the city, such as the recently-renovated Easterwood Park basketball court.
In a statement, Under Armour Senior Vice President Matt Mirchin said the company's goal was "to make all athletes better" and that the Baltimore Running Festival still fit neatly into that mission.
"The Baltimore Running Festival is a premier running event and we are committed to creating a memorable experience for every participant, whether they are from Baltimore or visiting for the first time," Mirchin said. "We want runners to put on their race shirt and remember what a great time they had in our hometown."
