11 running, fun run, and walking events in Gaithersburg, Maryland

This is the 33rd running of the Kentlands/Lakelands 5K Run, Walk, and Kid’s Fun Runs. The 5K course winds through the beautiful Lakelands and Kentlands neighborhoods before heading down Main Street to the finish line. Every 5K registration comes with a Dri-Fit crew neck race shirt (men's, women's, and kid's sizes available). Enjoy our post-race Merchant's Expo area while meeting with your friends and family!

Live entertainment on the course - local bands set up along the course to delight participants and spectators alike, making what is already a spirited and fun event even livelier! The event finishes with the awards ceremony, team awards (lots of family options), and raffle items donated by local merchants. Cash prizes for the top three male and female finishers.

Kids runs includes two distances - 200 and 500 meters! Cotton t-shirt, designed by a local child resident, with each Fun Run registration and a Kids area for a fun time after their event.

When you support the Kentlands/Lakelands 5K, you support all 14 community programs of the Kentlands Community Foundation — fueling arts, culture, education, and volunteerism throughout our community.

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.
