October 2026 5k race: how many porta potties for 300 runners and spectators?

Nina R.asked 8 viewsEvents & WeddingsUnits per personAda cluster ruleSpecial event permit5k raceEvent planning

I'm planning a 5k race for October 2026 with 300 total people, runners and spectators. The race starts at 8 AM, so we'll have a pre-race rush and a post-race crowd lingering at the finish line for about two hours. There's no alcohol, but we'll have a water station and light snacks. The units will be placed on grassy, level ground in a park, with easy truck access for delivery and service. I'm considering a mix of standard units and at least one ADA-compliant unit to meet the ADA 5 percent cluster rule. How many units should I rent for this peak usage, and should I add a handwash station for the food area?

For your 5k race with 300 people, plan for at least six portable toilets plus one ADA-compliant unit and a handwash station. The units per person guideline for a four-hour event suggests one unit per 50 to 75 guests, so six standard units for 300 people is a good starting point. You must include at least one ADA-compliant unit in the cluster to meet the ADA 5 percent cluster rule. A handwash station is essential when serving food, and placing it near the snack area encourages use.

Your event has a concentrated peak usage before and after the race, so the guideline number is adequate. The absence of alcohol and a relatively short duration means you do not need to add many extra units. Since the event is only a few hours, you will not need a service visit during the race. The rental company will deliver clean units the day before and pick them up after. Easy truck access and level ground in the park simplify placement.
