The pros, explained

A coach or a dietitian can work inside your race. They suggest, you decide: nothing they touch becomes real without you. And it is free, for them as for you.

🩺 Asking for a pro account

Professional

Coach, dietitian? You create an account in Le Cairn like everyone else, then ask for the professional account from your profile: your profession, your credentials — diploma, organisation, website, registration number — and a word.

I open the account on the strength of those credentials. That is all they are for: they are shown to nobody, neither your clients nor the site.

🚪 2 doors, never one

Route planner

An open pro account does not see anything yet. They ask to follow you; you choose which races are opened to them. Their parts — information, kit, nutrition strategy, split times… — are set once and for all on their pro account, and shown to you before you accept: “Can edit: …”. Race by race. You close it again whenever you like.

✍️ They suggest

Professional

In My athletes, they open the race and work in the editor, as you do. What they type shows in purple, and what the calculation derives from it in pale purple, marked “↻ recalculated”.

“Save” changes nothing: it opens the remark screen, which shows each field suggested, named in the words you will read — then asks why. That note is mandatory: a change without a word teaches nobody anything.

With the nutrition part, they see each runner's starred products and food reactions — what went down, what turned the stomach — above the plan.
While a race is live, nothing can be suggested: you do not rewrite the plan of someone who is running.

✅ You decide

Route planner

The suggestion reaches you in plain words, line by line, with its note:

A suggestion from Léa Martin

Field	Suggested
Prise nº 4 · Glucides/h	75 → 60
Prise nº 8 · Glucides/h	75 → 60

You tick what you keep, then Accept what is ticked — or Decline. A refusal touches nothing: until you have said yes, your race has not moved by a single figure.

🔒 What they never see

Everyone

3 things are never sent to them: the personal 6-digit codes, the runner's phone number and that of their emergency contact. Not hidden on screen — not sent at all: whatever reaches a browser can be read by whoever is holding it.

The private note you write about a runner does not reach them either, whatever part is open.

⚠️ Your runners asked for none of this. If your race carries people other than you, opening it to a professional gives them their names, race numbers and weight — and, if their account carries nutrition, their starred products, what they ate and how it went. They ticked no box: it is up to you to tell them. If you are not sure you have their agreement, do not open that race to a professional who has nutrition.

What does it cost? Nothing. The professional account is free, like the rest of Cailloux: no subscription for pros, no commission on your clients.

What is kept? The link between your 2 accounts — who follows whom, since when, which races are open — and their suggestions: the values, their note, your decision. Closing their access erases their pending suggestions.
