In addition to the races in classic technique La Diagonela (56km), La Pachifica (25km) and La Cuorta (6km) on Saturday, La Sfida (29km) in free technique provides an additional challenge on Sunday.
The start is in the Zuoz cross-country skiing centre and the route largely follows the Engadin La Diagonela and ski marathon route to the finish in Silvaplana-Surlej.
There is a combined classification with La Pachifica (25 km classic) and La Sfida (29 km free style). Participants who complete both races will automatically have their times added together for the skiathlon classification.
