The time limit for the half marathon is four hours. However, in order to complete the race faster than the roads are being re-opened to vehicular traffic, all half marathon participants must be able to maintain a pace of 13:45 per mile or faster over the first eight miles of the course. Any half marathoners finishing after the four hour time limit will not be scored as official finishers.
The time limit for the marathon is six hours. The course will close on a rolling schedule, with the finish line closing at approximately 1:55 p.m. Marathon runners must sustain a pace of approximately 13:45 per mile in order to finish ahead of the course closure.
