The Stone Mill 50 Mile Run showcases the beauty of both the Seneca Greenway and Muddy Branch trails in Montgomery County, Maryland.
Hundreds of runners, volunteers, and spectators take part in the day-long event due to its scenic trails within the populated Montgomery County. You can reach each of these participants, families, and friends by joining MCRRC as a sponsor of the Stone Mill 50 Mile Run.
The Sponsorship Packet for the 2025 race is COMING SOON! In the meantime, please contact the Race Director with any questions.
