15 years of running for the cause

The Leucan Ultramarathon will take place in May in the beautiful region of Saguenay–Lac-Saint-Jean. The event is much more than a simple sporting event! Runners and walkers will share an exhilarating adventure, take on impressive personal challenges and, most importantly, show their solidarity with children facing cancer. From its humble beginnings, this event has become a pillar of support for Leucan’s cause. 

Founded by avid runner Dave McMullen with the support of Richard Courchesne, the Ultramarathon, now strongly associated with the region, will be enthusiastically celebrating its 15th year.  Over the years, the dedicated members of the organizing committee (including Dave McMullen, Dave Bard, Pascal Morin, Guillaume Charest and Donald Dubois) have moved the project forward, never letting up in their commitment to the success and development of this outstanding sporting event.

Whether you’re a regular marathon runner or a beginner, a child or an adult, running with friends or coworkers, you’ll find an experience that’s right for you at the Leucan Ultramarathon. Join us for our free family activities in several areas of the region, open to everyone, whether you’re registered for the event or just interested in supporting the cause.
