The Charity Bibs of the Diable 20K allow you to take part in the race while supporting one of our two official causes:
How It Works
Step 1 – Choose your cause and start your registration
Go to the “Charity Bibs” section and select the distance of your choice. Complete your initial registration (it will remain incomplete for now—don’t worry, that’s normal).
Step 2 – Make your donation
You’ll receive an automatic email with links to both partner organizations. Choose your cause and make your donation or start a fundraising campaign.
Step 3 – Donation validation
Once your donation has been confirmed by the chosen organization, the Boréalys team will validate the amount and send you a new email with a personalized registration link.
Step 4 – Finalize your registration and payment
Depending on the total amount raised, you’ll be able to complete your registration and pay the remaining balance according to the scale below:
$250 to $749 = Regular price / $750 to $999 = 25% discount / $1,000 and up 50% discount
A minimum donation of $250 is required to obtain a Charity Bib. Deadline: July 24, 2026, or until all 70 Charity Bibs for the Diable 20K are sold out.
Step 5 – Confirmation
Once your payment is completed, you’ll receive an official confirmation email—you’re now registered for the race!
Donation Distribution :
75% of the funds raised go directly to the cause you support. 25% go to UTMB Care, a solidarity fund that supports local communities affected by natural disasters.
