Mile signs and clocks will be posted at every mile. Course clocks will be set to correspond with the 7:00 a.m. start time.
Water and Gatorade Stations
Water and Gatorade Endurance Formula (Lemon-Lime), the official on-course sports drink of the Chevron Houston Marathon, are available every 1.5 miles beginning at mile 2. The specialized Gatorade sports drink contains approximately twice the sodium of Gatorade Thirst Quencher (200 mg per 8 ounces), along with chloride, potassium, magnesium, and calcium to help sustain hydration by more fully replacing what is lost in sweat.
All hydration stations have Gatorade tables’ set-up first. To avoid the bottleneck at the first table, get your drink from a later table.
The last Gatorade table and last water table of each station are marked by a sign. Please keep moving even after you pick up your drink. If you wish to slow down to drink, do so after you have passed all tables. For your safety, take fluids only at the official stations. They will be protected by race security.
Both Gatorade and water will be available in the George R. Brown Convention Center before and after the race.
Course Aid Stations
Medical aid stations are available at every other mile beginning at mile 5. The aid stations are marked by large red tents with a white cross.
CLIF Shot Energy Zone
CLIF Bar is proud to be the Official Performance Nutrition Sponsor of the Chevron Houston Marathon. Look for the CLIF Shot® Energy Zone around Mile 21. Please refer to the official Chevron Houston Marathon course maps for the exact location.
Port-a-cans are located every 1.5 miles starting at mile 2, following the refueling stations.

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 1:25 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.
Walkers and Slower Participants
The Aramco Houston Half Marathon welcomes all those who can finish in the four hour time limit. If you plan on participating, but cannot average the necessary 13:45 per mile pace for the first nine miles and 18:00 per mile pace thereafter, please be aware that streets on the route will be reopened to vehicular traffic on a rolling schedule, as dictated by our permit.
