Enjoy spring at the U.S. National Arboretum during FONA's Flowering 5K. This run or walk will take you past garden collections brightly colored with spring flowers, over tree-lined rolling hills, and along streams winding their way to the Anacostia River. _Enjoy cherry blossoms, magnolias, and so much more!_



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 music will get you in the groove before and after the event. A professional photographer will also take photos of racers along the course (photos will be available 1 week after the race).



Strollers and dogs are welcome, but dogs must stay on a 6' non-retractable leash.
