This event is a blend of scenic trails and competitive spirit as runners and families gather for various distances. Starting early at 7 am on the crisp morning of August 9, race participants can look forward to a picturesque setting along the shores of Lake Tremblant.

Participants often gather in the charming town center before heading out onto the course. The event has been running since its inception and now boasts a strong tradition within the community, supporting local charities through participant fees. In recent years, thousands have participated across various age groups, contributing to both individual achievements and team spirit. Course venues include the Mont-Tremblant National Park, known for its challenging yet rewarding terrain. Runners will navigate through forested paths and open fields, with a mix of uphill climbs and downhill descents on a well-marked course that ensures safety.
