Harpeth Hills Flying Monkey Marathon

Registration opens for a one-week window and runners are selected through a weighted lottery, with approximately 300 spots available. The 2026 entry window closes August 8. Charity registration is also available for $120 and bypasses the lottery on a first-come, first-served basis.

The course accumulates roughly 3,500 feet of gain and 3,500 feet of loss across its multi-loop route through Percy Warner Park, making it a net-neutral but relentlessly hilly race. The repeated climbs are the defining feature of the course.

The race is intentionally small, with roughly 300 runners selected and around 273 finishers in a recent year. That intimate size is part of the appeal.

The race is held in late November, so expect a cold start typically in the upper 30s, warming into the mid-to-upper 50s by midday. Dress in layers you can shed and check forecasts closely, as temperatures in Nashville can swing significantly in November.

The race starts in Percy Warner Park, about nine miles southwest of downtown Nashville. Nashville International Airport is roughly 20-25 miles away, a 30-40 minute drive to the venue. Staying downtown or in Midtown gives you easy park access plus the city's amenities the night before.
