Tour du Lac Brome Sun Life is a two-day road running and walking event held at Lions Park in Knowlton, Quebec, located in the Eastern Townships. Taking place in June, it offers a range of distances, from a 1 km option to a half marathon, including 5 km, 6 km, 10 km, and 12 km races.
The event begins and concludes within the village, centering the day around Knowlton itself rather than a distant course. Over 2,500 participants attend annually, making this series one of the region's established races. Sun Life serves as the title sponsor, and two-day challenges are available for those seeking multiple race starts.
