This activity, practiced in the heart of nature - as here in the absolute calm of the white paradise of the Haut-Jura Regional Nature Park - recharges the body with vitamin D in a mountain air far from urban pollution. A natural doper, altitude also forces the body to produce more red blood cells to compensate for the depletion of oxygen and allows for an exercise beneficial for the heart, respiration, muscles and general endurance.
