On Saturday, August 22, 2026, at Maisonneuve Park, join us for an unforgettable 19th edition!
The 19th Edition of La Course TROIS, 2, 1, GO!, presented by Caisse Desjardins du Centre-est de Montréal, is RT21’s largest annual fundraising event. The money raised allows us to continue supporting our 1,120 members, over 400 of whom live with trisomy 21.
This event is also the largest gathering of families concerned by trisomy 21 in Quebec. It provides a wonderful opportunity to raise awareness and help attendees build a genuine support network.
For this 19th edition, there are several ways to support the cause:
- Participate in one of the four races at Maisonneuve Park;
- Create an individual or team fundraising page;
- Participate by donating to a participant’s fundraising page
- Make a corporate or individual donation to the organization right now.
