Ultra trail de Mont Blanc is a prestigious race held in Europe. In this race, trail runners all over the world get tested for the perseverance in finishing one of the toughest race in trail running history. Over the years, I watched Elite runners winning and losing the race, some elites even go on a DNF. JIM WALMSLEY , an American runner, finally won the UTMB after 5 attempts. He displayed GRIT and perseverance.
