The Under Armour Baltimore marathon is Baltimore's biggest marathon, and it has become a big success.
The race starts and finishes at Camden Yards, the Baltimore Orioles' stadium. The course goes by the Inner Harbor, Fells Point, and Federal Hill. It also goes through Clifton Park and Druid Hill Park and circles Lake Montebello.
For a extra incentive, do the Frederick Marathon in early May along with the Baltimore marathon and get a special "Maryland Double" medal.
