Travelling into Washington, DC is going to be difficult regardless of what you are there for. I gave the parking low ratings but truly that is not the race's fault. I ended up parking near the Armory where they have packet pickup and took the VERY easy Metro in to the Pentagon station. You have to be patient as this race is HUGE. So many people! So arrive early and bring some extra snacks and plan your bathroom break proactively. The race is fantastic though. So patriotic and you pass so many monuments along the way. Fast and flat course to boot! Would love to go back and do this one again.
