Event overview
The 2026 Summer Forest race takes place on June 27, 2026, at Prince William Forest Park in Triangle, VA. The event offers three distances:
- 5k
- 10k
- Half-marathon
The 5k is a trail run. The 10k is roughly half trail and half pavement. The half-marathon is mostly pavement (about 60%). The event awards points toward year-long series standings and the Spring Series. A virtual race option is available.
Logistics and race services
Registered participants receive a finisher’s coin, a technical (drifit) event shirt, and chip timing.
