Norway's Johannes Høsflot Klæbo will be seeking to increase his lead in the International Ski Federation (FIS) Cross-Country World Cup standings, when he competes in the sprint freestyle event in Planica in Slovenia.
Klæbo has won both sprint events this season - the classic in Ruka in Finland last month and freestyle in Swiss town Davos last weekend - and will be looking to make it a hat-trick tomorrow, prior to the team event on Sunday (December 22).
The 23-year-old has the most career sprint World Cup wins among men, with 18.
Italy's Federico Pellegrino has the joint-third most, with 13, and won the only previous sprint freestyle event held in Planica in January 2016.
Klæbo leads the overall FIS Cross-Country World Cup standings with 520 points.
Fellow Norwegian Emil Iversen is second on 448 points, while Russia's Alexander Bolshunov is third on 375.
