Color Run Course and Station Planner

The planner works out four things organizers usually guess at: where stations sit on the course, how much powder to order, how many volunteers each station needs, and how long the event runs. It shows its arithmetic, so you can check every number against your supplier's advice and your venue.

How the powder total is calculated

1. Participants in color = participants − those on the powder-free route.
2. Passes per participant = stations × laps with color. On a one-way route, each station is passed once.
3. Station powder = participants in color × passes × grams per dusting, plus your buffer (15% by default) for spills, wind and refills.
4. Finale powder = participants in color × finale packets each × grams per packet. Set packets to None if you are not doing a finale.
5. Total = station powder + finale powder, shown in pounds and kilograms, and split evenly across stations.

Arithmetic The pre-filled example: 400 participants × 4 stations × 1 lap with color × 50 g = 80 kg, plus 15% = 92 kg (about 203 lb), or about 51 lb per station.

Why published powder advice disagrees

Powder sellers' guidance ranges from a couple of ounces per person to a pound or more, a spread of roughly tenfold or more. The difference is not a mistake by one of them. It reflects how many stations a participant passes, whether volunteers dust from squeeze bottles or throw handfuls, whether there is a finale toss, the age of the participants, and how saturated you want shirts to look. A school event that colors each child once at four stations needs far less than an adult race that ends with everyone emptying a packet.

The planner's default of 50 g per dusting at four stations gives 200 g per participant, which matches the figure one powder supplier publishes for primary-school color runs, in an FAQ hosted by Coolum State School. The same supplier lists 200 to 250 g for high school and 400 g for adult events. Treat it as a starting point. Enter the amount your own supplier recommends and compare. The color powder buying guide explains the trade-offs and includes our dated price check.

Station spacing and the course

On a loop, the planner spaces stations evenly and places the first one half a gap from the start, so nobody is colored before the start line clears. On a one-way route, it divides the route into equal parts and leaves the finish clear. For the example 400 m loop with four stations, stations sit 50, 150, 250 and 350 m from the start, 100 m apart.

The planner warns when stations are closer than 40 m, a rule of thumb rather than a published standard. Closer than that, powder from neighboring stations tends to drift together into one long cloud, which is harder on eyes and breathing and gives volunteers no clean air between stations. Wind direction matters as much as spacing: the course and color station guide covers where to place stations relative to buildings, parking, drains and the first aid table.

Volunteer counts

The volunteer table uses rules of thumb you can adjust:

Role	Rule used	Example (400 participants)
Station leads	1 per station	4
Applicators	Stations × sides × applicators per side	16
Refill runners	1 per station	4
Start and wave marshals	2	2
Finish and water	1 per 150 participants, at least 2	3
First aid and eyewash	1, or 2 over 300 participants	2
Powder-free route guide	1	1
Course marshals	2 per km of total course, at least 2	4
Cleanup crew	2 per station, at least 4	8
Lap counters	Only on multi-lap loops with per-lap pledges	0 (4 if per lap)
Total		44

With flat gifts, the planner's default, the example needs 44. Turn on per-lap pledges and it adds four lap counters, for 48. When you are short, cut a station before you cut a safety role: first aid, the powder-free route guide and station leads should be filled first. The color run volunteer guide has role descriptions and a briefing script.

Waves and total time

Participants start in waves so stations never face a crowd. Total time = the last wave's start + the time one participant takes to finish the course. The course time is the total distance × your pace. For the example, four waves of 100 start six minutes apart, and each takes about 16 minutes to walk 1.6 km at 10 minutes per km, so the last wave finishes about 34 minutes after the first starts. Add time for the welcome, the finale and dusting off before anyone goes indoors.

Printable station cards

"Print station cards" prints one card per station with its position, its share of the powder, and the station rules every applicator follows: color below the shoulders and never at faces, stop for anyone who says stop, no color on the powder-free route, pause when wind carries powder toward people or buildings, no flames, smoking, grills, sparklers, fireworks or gas-powered equipment anywhere near powder, powder stored sealed, dry and away from heat, and dry cleanup with nothing washed toward drains. The reasoning behind each rule is on the color powder safety page. For printed role cards for every volunteer, use the download below.
