Friends of the National Arboretum Fall 5K 2026 — Washington, DC

Enjoy autumn at the U.S. National Arboretum during FONA's Fall 5K. This run or walk will take you past garden collections brightly colored with fall foliage, over tree-lined rolling hills, and along streams winding their way to the Anacostia River. This race is not only scenic, but also safe and secure. All roads are closed to cars during this race so you can safely enjoy running or walking through this 451-acre urban green space. A professional race announcer will call out runners as they cross the finish line and there will be music before and after the event to get you in the groove. Strollers and dogs are welcome, but dogs must stay on a 6' non-retractable leash. A 20% discount is available to all furloughed federal employees, veterans, active duty, and reserve military members (email info@fona.org for the discount code). All FONA members can also receive a 20% discount as part of their member benefits (if you're already a member, check the latest member newsletter for the discount code). Please make a donation of any amount to become a FONA member.
