Is anyone coming from the Tysons Corner area that would be willing to carpool. Public transportation to Woodbridge or directly to Fountainhead Park doesn't work and especially not that time in the morning.
With a first start at 8am, you will want to be onsite between 6 and 7 am. There is a shuttle to catch from parking, athlete check-in, warm-up, bag drop, necessities, and a 1.3 K walk to the start. Id you want time to look at the model or explore the warm up area - allow more time.
