A race with 500 runners needs restrooms placed at the start corral, the finish chute and at least one aid station along the course. San Rafael Porta Pros stages standard units and ADA units at each point and pulls them same-day once the course clears.
Race restroom counts don't follow a construction crew formula, but OSHA 1926.51(c) is still the baseline planners lean on: 1 toilet for every 20 people works for a static crew, and race organizers scale up from there because runners cluster hard at the start line and thin out along the route. For a typical 5K through downtown San Rafael, that means heavier placement near the corral and lighter coverage on the back half of the course. A marathon with a few thousand entrants and spectators needs restrooms clustered at the start, staged every couple of miles, and doubled at the finish festival. ADA Standards section 213.2 requires at least one accessible unit in any cluster, never fewer, and 5 percent of the total where you're setting several together. We work from your runner count and course map rather than guessing, and we'll tell you straight if you're under-ordering. Our restroom rental checklist walks through corral sizing, aid station spacing and finish-line crowding, and it's worth a look before you lock a layout. Races in Larkspur, 5.1 miles southwest of San Rafael, and San Anselmo, 4.3 miles west, run the same math even at smaller field sizes.
Put them where people already stop: the start corral, every aid station, and the finish chute. That's the short answer. Course marshals hate units dropped mid-route where they block a lane or sit on a blind curve, so we walk the map with race directors before delivery day. A standard unit sits about 44 by 48 inches on the ground, small enough to tuck against a curb or a fence line without eating up the running lane. Roll-off and trailer deliveries need about 60 feet of straight clearance behind the truck, which matters if your finish line festival also needs a construction dumpster or a temporary fence for crowd lanes. If your race routes near a job site or a venue running its own light tower or generator, ask how to brace a temporary power pole before race morning. A pole that isn't guyed or staked can shift under wind loading near a crowd corridor, and event staff should confirm bracing with whoever supplies the power before gates open. We coordinate our placement plan around that kind of infrastructure so nothing ends up fighting for the same six feet of sidewalk. For bigger finish-line footprints, a restroom trailer at the VIP or medical tent gives staff a real door and sink instead of a standard stall.
Race pricing runs by event day, not by the week, since most races need units delivered, serviced once mid-event for longer races, and pulled the same day.
| unit | event rate | notes |
|---|---|---|
| standard | $200 to $800 | per event, scales with count and distance |
| trailer | $2,499 to $3,899 | per event, includes attendant-ready setup |
| delivery_fee | $100 to $500 | per day, distance-dependent |
A weekend two-day race runs closer to the weekend band on standard units, and most race organizers still land inside the per-event range shown above once headcount and mileage settle. We quote the full course, not each stop separately, so you get one number instead of five invoices. Ask about our emergency porta potty add-on if your registration count jumps in the final week, since we can usually add units to an existing route order without re-running the whole delivery plan. For multi-day festivals paired with a race, our event restroom and festival restroom pages break down staffing and servicing separately from the race-day corral count.
Book as soon as your course map and runner count are set, ideally weeks out, since race weekends compete with weddings and festivals for the same trailers and standard units. San Rafael fills fast on race season Saturdays. Confirm placement with our team once your permit and road closure map are final.
Yes. Aid stations handling food or gel packets benefit from a dedicated handwashing station rather than sanitizer alone, and 29 CFR 1910.141(d)(2) requires soap and a towel or dryer, not sanitizer, for compliant handwashing setups.
Yes, for marathons and multi-hour events we can schedule a mid-race service pass. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for light use, but race-day crowding calls for a same-day pump-out instead.
We cover routes that cross into San Anselmo, 4.3 miles west, or Larkspur, 5.1 miles southwest, on the same delivery run. Check our service areas page or San Anselmo page for that side of the course.
Placement in the public right of way needs confirming with the city before race day. We can deliver once your permit is issued; check our porta potty permit guide for what to ask the city.
Yes. San Rafael Porta Pros delivers marathon and race restrooms across San Rafael and the surrounding metro, with same-day and next-day drop-off available on most orders.
Pricing depends on the unit and how long you need it. See our cost breakdown and request a free quote for an exact figure.
Standard rentals include scheduled service — a pump-out, a clean, a restock and fresh deodorizer. Busy or hot-weather sites can be serviced more often.
