Work out your race aid stations to the detail, not by eye.
Know exactly how much water, sports drink, fruit and solids you need at every point of your race, based on your real entrants, the temperature, the humidity, the forecast rain, the kilometres and the number of aid stations. With the approximate cost of each point and a final shopping list in commercial formats, ready for your supplier.
Guessing your aid stations by eye is expensive (in money or in thirsty runners).
What worries you most when supplying a race:
You run short of water at the hottest point and the runners complain.
You buy too much just in case, and end up throwing away whole drums and bags of fruit.
You don't know how to go from "litres needed" to drums, packs and bottles you can order from the supplier.
You reach the shop not knowing the real budget the aid stations will cost you.
Heat, humidity and rain change the whole calculation and you don't know how to adjust it.
This module does the technical maths for you and hands you the shopping already sorted, in formats you can order as-is.
Everything you can do
Real entrants or full forecast
Calculate on the entrants you already have or on the event's full expected cap, whichever you prefer.
Temperature and humidity
Fluid intake rises with heat and humidity; the calculation adjusts it automatically.
Rain forecast
Rain lowers how many participants turn up; the calculation takes it into account so you don't over-buy.
Kilometres and number of aid stations
It splits the total consumption between the points by distance and by how many aid stations the race has.
Each point's location
An aid station at a summit, on the flat or downhill doesn't use the same: the calculation tells them apart point by point.
The race discipline
Running, MTB, trail or a walk: each profile has its own pattern of liquid and solid intake.
Real commercial formats
The system turns the litres and grams needed into 8 and 5 L drums, bottle packs, sports-drink bottles, cup packs, tablets and bags: what you actually order from your supplier.
Cost calculation
Indicative market prices you can edit. You know the approximate cost of each point and the aid-station total before buying anything.
Final shopping list
A single list with everything you need for the whole race, adding up every point, with the total estimated cost.
What you'll use it for
🏔️ Trail and mountain with several points
Different aid stations at the summit, on the flat and downhill, each with its own calculation and its own shopping list.
🚵 MTB and road
Intake profiles built for the bike, with their own liquid and solid needs compared to running.
☀️ Races in high summer
When heat and humidity send consumption soaring, the calculation reflects it automatically so you don't fall short.
💰 Closing the budget before buying
With the total estimated cost, you know what the aid stations will cost you before placing the order with the supplier.
🧑🤝🧑 Coordinating the person in charge of each point
Give each volunteer their PDF sheet, with what they need to buy or prepare for their aid station only.
A PDF report ready to hand out
- ✓ One sheet per aid station, made for whoever runs that point.
- ✓ Quantities already with the safety margin included, no extra maths.
- ✓ The approximate cost of each point, to split the budget between stations.
- ✓ At the end, the full shopping list and the overall cost of all the aid stations.
- ✓ It's generated on the spot and downloaded; if you make last-minute changes, you can generate it again.
- ✓ Points with no products marked (say, the finish if it has no aid station) don't appear, to avoid confusion.
It's this easy
Define your aid stations: location, products and prices.
Set the forecast temperature, humidity and rain.

Frequently asked questions
Does it calculate on the entrants I have or on the full cap?
Whichever you choose: on today's real entrants or on the event's full forecast.
How does the weather come into it?
Temperature and humidity raise fluid intake; rain lowers how many participants turn up. The calculation adjusts both automatically.
Does it tell the different aid stations apart?
Yes. It splits consumption by kilometres and by the number of aid stations, and adjusts each point for whether it's at a summit, on the flat or downhill.
What format does the shopping list come in?
In real commercial formats: water drums, bottle packs, sports-drink bottles, cup packs, tablets and bags of solids. What you can order as-is from your supplier.
Does it work out the cost too?
Yes. With indicative market prices you can edit, you get the approximate cost of each point and the aid-station total.
Can I download it as a PDF to hand out to volunteers?
Yes, one sheet per point plus the final shopping list, all with the cost included.
Does it work for MTB, trail and running?
Yes, each discipline has its own profile of liquid and solid intake.
From the technical maths to the shopping list, with no spreadsheets.
Entrants, temperature, humidity, rain, kilometres and number of points: it all goes into the calculation. Out comes a shopping list in real formats, with the total cost, ready to order.
