October 2026 5k race: how many porta potties for 500 people?
I'm organizing a 5k race in October 2026 with about 500 people total, runners and spectators. The event will run from 8 AM to noon, so four hours. We'll have a water station for runners and a food truck for spectators, no alcohol. The course is in a city park with grassy, level ground, and a service truck can drive right up to the placement area. I'm deciding between standard units and maybe a deluxe unit or two near the finish line for nicer facilities. How many porta potties do I need for this crowd? Should I include an ADA-compliant unit even if we don't have registered wheelchair participants?
