Roll out of Lussac-les-Églises and let the ride unfold along the water. You'll cross the L'Asse, then the Gartempe, the Salleron and finally the Benaize, each river ticking off another stretch of the loop. The route runs 81.3 km with 498 m of climbing, and the surface stays paved the whole way round. Back into the start village with four rivers behind you.
