About this race
The first edition of a race with a radical concept: the backyard ultra. Each hour, you'll cover a unique loop of approximately 6.704 km with 50mD+. You must be at the start line when the signal sounds, or you're out. Here, you run to endure. Your mental strength will be tested in the Sillé-le-Guillaume forest. As they say, "In the end, only one will remain!" You will be alone facing your destiny during the Sillé Backyard Loop, but the base camp atmosphere will help you push through. Prepare to fall in love with Sillé-le-Guillaume, and be warned, local specialties will surprise your taste buds.
