Les Foulées d'Isidore is a race held in early April in Lezennes, a town in the Nord department near Lille in Hauts-de-France. The event offers runners several road race options: a 5 km, a 10 km, and a half marathon. A 5 km walk is also available for those who prefer not to race. Dedicated courses are provided for children and junior runners, making the day suitable for families and adult participants alike.
The routes traverse urban streets and a public park within the Lille suburbs. The half marathon is the most popular distance, and the shorter races cater to newer runners and local club members. Its motto is “À pas de géant !”, and it is recognized on the regional racing calendar as a small-scale community event, with the previous edition attracting over 100 participants.
