Speedriding is an efficient mix of skiing and paragliding. Small and fast kites make you leave your traces on inclines hardly reachables just by ski, catapulting you through intrepid rides across breathtaking flights. Luca and Mattia, with little money but huge passion, have clear in mind what their goal is: freeing their kites for a trilogy of first world descents from the 4000m peaks Mont Blanc, Monte Rosa and Matterhorn. “Riding 4000” is their story. A story that talks about sport, speed, mountain and passion. Many stories that narrow down to one, the most important: friendship.
