The Woodlands Marathon has multiple events, and Amateur Radio Operators are asked to assist with the Full (26.5 mile) and Half (13.1 mile) events.
Both the Full and Half Marathon events are using the same roadways, just that the Full Marathon will be twice around, while the Half Marathon will only be once around.
This twice around situation should mean that after the full marathon's last participant has done the first loop, we can start releasing operators as that last participant works their way around the 2nd time.
This may mean that those toward the end of the course are in for a rather long stint, so it will be helpful to have some operators that can allow other operators to be swapped out during the event.
Note: You are welcome and encouraged to bring others with you. It's often a great family outing, as long as that does not interfere with your ability to perform your assigned duties.
Here is a diagram that shows the course in general.
