About the Friends of the National Arboretum Fall 5K
The course winds through the U.S. National Arboretum, moving past garden collections deep in fall color, over rolling tree-lined hills, and along streams that drain toward the Anacostia. All roads inside the grounds are closed to traffic for the race, so the whole route feels open. Dogs on short leashes and strollers are both allowed.
Packet pickup happens race morning at the Capitol Columns, which is also the start line. Several parking lots are spread across the grounds, each a short walk from the start. There is no race-day registration, so you need to sort your entry ahead of time.

The Friends of the National Arboretum Fall 5K has been held every year since at least 2022. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
