The Chevron Houston Marathon and Aramco Houston Half Marathon use a single start line for both races. The start features four corrals with the first corral starting at 7:01 a.m. Corrals B and C will follow the A Corral using a pulsed start method – three minute time intervals separating the corrals – to reduce course congestion. Corral D will follow immediately after the C corral with no pulsed intervals. Corral assignments are determined by the predicted finish time of each runner indicated during registration. Corral A seeding is by request only, and the deadline to submit a qualifying time is November 30, 2018. Please log in to your participant account to add your qualifying time.

Course Time Limit
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.
Under no circumstances may participants be on the course before the official start time. Beginning before the official start time will result in disqualification. If participants choose to continue running after the course closes, they do so at their own risk and will be asked by the Houston Police Department to move off the streets.
No times are recorded after the four-hour and six-hour time limits for the half marathon and marathon, respectively. Participants finishing over the four or six hour time limit (chip time) will not be considered official finishers.
