Marathon toilet logistics
Build the queue into your schedule and know the on-course alternatives.
Before race morning
Locate toilets near transport, the start and the course on the official map. Check whether a line is inside or outside the secured corral area.
On the clock
Treat a toilet stop as elapsed time and let the race unfold after it. Record the stop in your debrief so you can distinguish a pacing issue from a logistics issue.
Example fallback
If the start queue threatens your corral closing time, use the alternative you identified on the map and check the organiser’s rules for late entry into waves.
