Porta Potty Rental for Races and Fun Runs in Phoenix
A race with 4,000 runners and spectators over 4 hours comes out at about 22 units on the PSAI chart. The Maricopa County minimum for that crowd is 40. Start lines need the most units, since nearly everyone goes in the hour before the gun.

The start is the crunch. Put most units near the start corral and a few at the finish and along longer courses.
Courses on public streets need city permits. Units cannot block sidewalks.
