Beginning in 2017 we have used a wait list model to help us get exactly the allowed 369 runners on the start line. Once the field of 369 runners has been set, 50 more applicants will be selected from the lottery for an ordered general wait list. If any entrant withdraws from the race for any reason, the spot will be given to the next runner on the general wait list.
The only exception to this is if a sponsor or aid station designated runner withdraws from the race; the sponsor or aid station will be allowed to designate another qualified runner who has qualified and applied for the Run. If no replacement is designated, then the spot will be given to the next runner on the general wait list.
