Course and course services will be open to all runners that remain within the 6 hour finish cutoff pace. Sweep runners beginning as the final starters at 7:30am will mark the end of the race for course and finish line services. Any runners who fall behind the sweep runners will not be guaranteed any course or finish services (eg aid stations, medical services, finisher items, etc.). There will be sweep and drop out transportation provided at the back of the race and at the relay exchange zone to transport runners to the finish line as needed.
