Plan on 1 toilet per 20 runners for the first hour and add units for every hour past that, since a 5K crowd clears fast but a half marathon strings people along the course for 2 to 3 hours. Richardson Porta Pros stages standard portable toilets at the start line, mid-course and finish for race organizers.
Start with the field size and the course length. A tight 5K with 300 runners and a start/finish in the same lot can run on 6 to 8 standard units clustered near the corral, following the same logic OSHA lays out for fixed job sites: OSHA 1926.51(c) sets the baseline ratio at 1 toilet per 20 workers, and race directors in Richardson use that same math as a starting point even though runners are not employees under the standard. Half marathons and full marathons need units spread along the route, not just at the start and finish, because a runner is not walking back to the start line for relief.
Aid stations every 2 to 3 miles are a natural spot for a single unit or two, and you will want at least one ADA accessible porta potty at the start, at the finish and at any aid station reachable by the accessibility van. ADA Standards section 213.2 requires that at least 5 percent of clustered units be accessible, with a minimum of one, and ADA Standards section 304.3.1 calls for a 60 inch turning circle inside that unit. If your race pulls a spectator crowd along the barricaded route, budget separately for them using our how many porta potties do I need guide, since spectators do not move through the course the way runners do.

Set them off the running lane, behind any OSHA 1926.202 barricade line, and never blocking a water station or timing mat. A unit needs firm, level ground, and ADA Standards section 302.1 calls for stable, slip-resistant surfaces at any accessible unit, which rules out loose gravel or wet turf for that specific placement. Our porta potty placement guide covers ground prep in more depth.
Finish-line areas draw the heaviest use in the shortest window, so cluster more units there than the per-runner math suggests, and add a handwashing station or two near any food or medical tent. If the race runs through Richardson and loops toward the edge of town, coordinate pickup timing with our service areas page, since a course that stretches toward Murphy, 8.5 miles northeast, or Sachse, 10.3 miles east, may need a second delivery truck staged closer to the far turnaround. For races that also need a finish-line command post with lighting and power, our light tower rental and temporary power pole pages cover that setup, and if you are running a generator or power pole near the finish tent, brace it against wind and foot traffic the same way you would brace a construction site power pole: guy it at two points minimum, keep the base plate on level ground, and route any cable across a walkway under a ramp or mat rather than letting it lie exposed where a runner could catch a foot. That is the short answer to how to brace a temporary power pole for a race-day setup: two guy points, a level base, and cable routed away from foot traffic. A poorly braced pole near a crowded finish chute is a bigger liability than a missing restroom.
Water and handwashing matter as much as the toilets themselves. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, and while runners are not covered by that clause, your volunteer and medical staff working the course are, so plan water and a handwash setup for them regardless. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at any washing station, not sanitizer alone, so pair your portable sink rental or handwashing station rental with actual soap and drying, not just a gel dispenser.
For races with sponsor tents, VIP areas or a runner village, a restroom trailer rental upgrades the experience past a standard unit, and our 2 stall restroom trailer fits smaller elite or sponsor areas well. Larger races in Richardson sometimes pair a 4 stall restroom trailer at the finish with standard units along the rest of the course. Check our event restroom rental page for the broader planning framework, and see festival restroom rental if your race weekend includes a packet-pickup expo or post-race festival.

| trailer | event | 3500 |
Pricing runs by event day, not by the hour, and a multi-day race weekend costs more than a single Sunday morning race. See our full porta potty rental cost breakdown for other duration options.
Two to four weeks out is comfortable for most races, longer for a marathon with 20 or more units across a multi-mile course. Delivery trucks need routing time to reach every aid station before the field starts moving, and Richardson race organizers coordinating with nearby Wylie, 15.2 miles east, often add extra lead time for the drive.
Not safely once runners are on course. Units get placed before gun time and serviced after, not relocated while barricades are up and the route is active. Plan your final layout during the walk-through, not race morning.
They need separate counts. Spectators cluster near the start, finish and any viewing point along the barricade, while runners spread across the whole course, so use our how many porta potties do I need guide to size each group separately rather than combining them into one number.
Placement in the public right of way needs confirming with the city before race day. Check with Richardson's permitting office directly, since dumpster permit requirements and porta potty placement rules are handled separately and neither is something to guess on.
Yes. Richardson Porta Pros delivers marathon and race restrooms across Richardson 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.
