[1] Since 1995, along the Sentiero Roma, runs the Trofeo Kima, a high altitude marathon considered one of the most demanding of the skyrunning world panorama.

The trophy is dedicated to the memory of Pierangelo Marchetti "Kima", the mountain guide of Valtellina, who died in 1994 during a rescue mission.

The route takes place on a distance of 50 kilometers with more than 3800 meters of altitude difference.

The winners take the entire route, counter-clockwise, starting and arriving at Filorera, in about 6 hours and 30 minutes.
