Is Bi-Pedal Best?

Via Francigena #10 of 20. Physics demands that when going up a steep hill you lean forward, especially if you have a pack on and don’t want to fall backwards, which I did. At one point the path became almost a 60 degree angle, somewhere between stairs and a ladder. I had leaned so far forward that with my knuckles grazing the ground it seemed best not to fight it and go full quadruped, gloves or no gloves.
