Celebrating its 15th Anniversary and this one keeps getting better! With five distances (full, half, four-person relay, 5K and fun run) to choose from, and all runners snagging a great Under Armour shirt for participating, this is one you can’t miss. Highly motivated runners can earn extra swag by completing the Maryland Double or the King Crab Challenge by running in other Corrigan Sports races. Sign up fast as the races sell out every year. You won’t want to miss the 15th Annual Baltimore Running Festival.
