This classic ride takes one on a grand circle up and over the mountains which form the western wall of the Valley of Oaxaca. It is not for the faint of heart, as there is over 1500 meters (5000 feet) of climbing along the route, which stretches for 88.7 kilometers (55.1 miles). Someone with stout legs and lungs – or riding an ebike – can accomplish the loop in five or six hours time. The loop can be ridden equally well in either direction.
