Chevron Houston Marathon approximate course elevation map.

Aramco Houston Half Marathon approximate course elevation map.

The Chevron Houston Marathon and Aramco Houston Half Marathon use a single start line for both races. The start features five 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. Corrals D and E 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. Please log in to your participant account to add your qualifying time.

Mile signs and clocks will be posted at every mile. Course clocks will be set to correspond with the 7:01 a.m. start time.

Water and Gatorade Endurance Formula (Lemon-Lime), the Official Sports Fuel Provider of the Chevron Houston Marathon, are available every 1.5 miles beginning at mile 2. The specialized is formulated to help sustain hydration by more fully replacing what is lost in sweat.

All hydration stations have Gatorade Endurance tables set-up first. To avoid the bottleneck at the first table, get your drink from a later table.

Gatorade Endurance Energy Gel stations will be placed at approximately mile 7 of the Chevron Houston Marathon and Aramco Houston Half Marathon and again at approximately mile 18 of the Chevron Houston Marathon.

The last Gatorade Endurance 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 Endurance and water will be available in the George R. Brown Convention Center before and after the race.

Medical aid stations are available at every refueling station starting at Mile 2. The aid stations are immediately before the refueling station.

Port-a-cans are located every 1.5 miles starting at mile 2, following the refueling stations.

Should you find yourself unable to complete the entire course due to either physical or time limitations, the Support and Gear (SAG) Team is available to assist you. SAG vans will be available to pick up any participants who need a ride back to the George R. Brown Convention Center. Designated pick-up points for SAG vans are located at every Medical Aid Station. Go to the nearest Medical Aid Station for SAG pick-up. SAG vans will run approximately every 15 minutes from each Medical Aid Station. All SAG vans and buses will have SAG Race Crew onboard to provide information on the services available to participants upon return to the GRB. There will be water and Gatorade for hydration on the vehicles, and the vehicles will be climate controlled.

NOTE: Pick-up by our SAG vans is only available at Medical Aid Stations or by the final SAG van that tails the race route as streets reopen to traffic.

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.
