Is there a course time limit?
The course completion time limit* is six (6) hours.
For transportation, security, and general marathon operational constraints, closing times will be enforced for each section of the marathon. If you do not reach the next section before it closes, you will not be allowed to continue the race. On any section of the course, if you have fallen behind considerably or are considered clearly unable to make the next gate or finishing line before the time limit, you may be instructed by marathon officials to stop running even if there is time remaining.
