Mackyard Ultra : 5th Annual edition
The Baltimore Road Runners Club presents the 5th annual Mackyard Ultra, a sanctioned backyard ultra held at Shawan Downs in Cockeysville, Maryland. The event follows the backyard ultra format commonly called "last man standing."
Participants run a measured loop of 4.1667 miles each hour. Each completed lap is called a yard. Runners repeat the loop every hour until only one participant completes a lap alone; that runner is recorded as the winner and the only official finisher.
The course uses the Shawan Downs cross country layout and is run on grass. The loop includes noticeable changes in elevation and direction, with ups, downs, twists, and turns on an out-and-back configuration.
Registration opens August 2, 2026 and closes October 28, 2026. The posted registration fee is $25.00. The event is hosted at 1401 Shawan Road, Cockeysville, MD 21030. Visit the organization's website for the most recent information.
