The San Antonio Marathon & Half Marathon have timed course cutoffs: 1 for the Half Marathon and 3 for the Marathon.

• Half Marathon: 4 hours (18:19 per mile)
• Marathon: 7 hours (16:01 per mile)

Marathon participants must remain in their assigned corrals and should not drop back, as cutoffs are strictly enforced. Cutoff times are based on your timing chip, not gun time. In the event of a race delay, cutoff times will be adjusted. Final cutoff details are in your Race Week Information Guide.

Cutoff #1 – Mile 6.3: E Mulberry Ave & Red Oak Road, just before entering Brackenridge Park. Participants who miss this cutoff will be redirected to Broadway.

Cutoff #2 – Mile 9.7 (Marathon only): Wilson St & N New Braunfels Ave at the course split inside Fort Sam Houston. Marathon participants who miss this cutoff will be reclassified as Half Marathon participants.

Cutoff #3 – Mile 10.9 (Marathon only): E Hildebrand Ave & N New Braunfels Ave. Marathon participants who miss this cutoff will be turned around and directed back south on the course.

The course time limit starts when the last corral crosses the start line. If your pace drops below the minimum (Marathon: 16:01/mile, Half Marathon: 18:19/mile), you have a few options:

• Increase your pace to stay within the limit.
• Ride a SAG vehicle to a later point on the course and continue. You can still finish and receive a medal, but will be listed as DNF in the official results.
• If you cannot or choose not to continue, the SAG vehicle will take you to the next Medical Station for transport back to the finish.
