Roll out of Bussière-Poitevine and let the ride unfold along the water. You'll cross La Blourde, then La Vienne, followed by La Petite Blourde and finally La Gartempe, each river ticking off another stretch of the loop. With 82.0 km ahead and 527 m of climbing, the route stays entirely on paved surface from start to finish. Four rivers, one village, and the road back home.
