Welcome to the Seneca Creek Greenway Trail Marathon & 50K, where you will experience some of Montgomery County's finest single-track trails. This is a challenging, but beautiful run for all!

The Seneca Creek Greenway Trail Marathon and 50K is a low-key, low-priced, and fun-filled event along the beautiful Seneca Creek Greenway Trail and parallel trails. Marathon and 50K participants will have the option to choose their final distance during the race (either stop at the finish line for the "marathon" or keep going to complete the 50K).

! DETOUR ALERT ! Due to the bridge on the Mink Hollow Trail being under reconstruction, there will be a detour on both the outbound and inbound course routes. Please refer to the map under the "Course & Logistics" tab for a map showing the detour. The trail, including the detour, will be marked on race day.

All participants will receive a custom race bib, short-sleeved tech shirt, and a finisher's medal!

Shaare Torah Jewish Community, Prince of Peace Lutheran Church, The Interfaith Families Project of Greater Washington, Trinity Lutheran Church, and the Ahmadiyya Muslim Community are proud to partner for the tenth annual Montgomery County Interfaith 5K. Our goal is to bring together communities of faith in the county so people from diverse backgrounds can join forces to share a fun and health-promoting activity, teach tolerance through exposure and friendship and enjoy each other’s company.

The Montgomery County Interfaith 5K is an inclusive event, designed to bring together people of different backgrounds to meet, socialize and work together to better the entire community. While many attendees are people of faith, the event respects all backgrounds and does not embrace any one religion or belief system. Religious services, proselytizing and preaching are not part of the public program and should not be practiced at the Montgomery County Interfaith 5K.

Register as part of a team! Teams that have 12 or more registrants as of August 24th can have a table in our race festival area. Register by August 9th to guarantee a shirt.

The 2026 Montgomery County Interfaith 5K will continue to donate its proceeds to support the local Montgomery County community. This year profits will be donated to Gaithersburg Help and C-4.
