Excellent organization, polite and impressive military presence, great volunteers, challenging and well-marked course(s), easy parking and logistics. Very cool fly-overs by various AF aircraft - different each year!
Expect a great race environment, as proven by the consistent popularity of this event (all distances). The USAF is very experienced at putting this race and it shows. Not an easy course - rolling, climbs, and false flats abound. Pace yourself conservatively as climbs in beginning AND end will be challenging. Weather can also be a factor, heat and humidity are generally felt, especially as the race progresses.
Plenty of lodging options near-by, but reserve early. Bring BAGGIES to protect running shoes from getting wet from the short walk from grass field parking area to pavement approach to start area. Also allow time for security check, etc.
By AMB about 2016
Rolling course and some tough hills at beginning and mile 21. Unfortunately, the weather was just brutal - super high humidity and high temps. There was a storm before the run that cause a delay till 8 AM. Once it finally got started, the sun came out and baked the wet roads, producing 100% humidity that sucks the life out of you. The course itself is fine and volunteers were outstanding. But the weather and air quality were a major challenge. I met people who could not even complete the 1/2 marathon. Some reportedly had collapsed. 20th Anniversary medal was spectacular. Other than the weather, it was very well run, except you had to walk nearly a mile to the buses after the finish.
This is technically a summer marathon, so make sure you are prepared. Conditions for 2016 were the worst I've ever encountered of my 17 completed marathons and this was my first AF marathon.
