La Route du Sourire in Lestrem is a small charity running and walking event with low-cost entries supporting a local cause. It offers several options in one morning: a 30 km trail-style race, a 10.9 km run, a 5.1 km run, and walking routes, with starts from 08:00 to 10:30. Entry fees range from 4 EUR for the walk to 15 EUR for the 30 km, with all registration fees donated to beneficiary associations Louane conte CDKL5 and Captain Louis.
The longer routes feature a mix of surfaces: the 30 km course is 60% trail, the 10.9 km is half trail, and the 5.1 km includes 30% trail. The event also provides activities for families, including children’s animations, a participant village, and a tombola for runners. Recent editions have seen hundreds of finishers, growing from 660 to 1,250, demonstrating its local appeal.
