About the DC Half

Pacers Running organizes DC Half as a dedicated half-marathon event with its own date, course and results. It is separate from the Rock 'n' Roll Washington DC Half already represented in production.

Course

The road route starts and finishes in West Potomac Park and uses central Washington corridors near the Potomac. The profile is built for steady pacing, but river wind and exposed stretches can shape race day.

Race-day weather

Late September in Washington can still be warm and humid, though cooler mornings are possible. Runners should avoid assuming fall conditions until the race-week forecast is clear.
