Starting from Salle Henri Brouillard in Guichen at 8 AM, the Randonnée de la Vallée du Boël is organized by VTT Club Vallée du Boël. The event includes mountain-bike rides, gravel rides, and walking loops. Registration is available on-site, catering to families, beginners, experienced cyclists, and those seeking a countryside walk.
The VTT routes span 20, 24, 36, and 48 km, with the 20 km route designed to be less challenging for families and novice riders. The cycling routes traverse paths near Pont Réan, Bruz, Laillé, Bourg des Comptes, and Guichen, incorporating new sections. The gravel option provides 45 km and 75 km circuits extending towards Saint-Senoux, Pléchatel, and Saint Malo de Phily. For walkers, there are three loops measuring 11, 13, and 17 km through the countryside surrounding Pont-Réan.
