2019–20 Tour de Ski

The 2019–20 Tour de Ski was the 14th edition of the Tour de Ski and part of the 2019–20 FIS Cross-Country World Cup. The World Cup stage event began in Lenzerheide, Switzerland on 28 December 2019 and concluded with the Final Climb stage in Val di Fiemme, Italy, on 5 January 2020. The tour was the third tour starting in Lenzerheide. The last stage known as the Final Climb was held as a mass start for the first time. A points standing replaced the sprint standing from previous editions.

Alexander Bolshunov became the overall winner, surpassing Sergey Ustiugov and Johannes Høsflot Klæbo. He became the third Russian to win the Tour de Ski. In women's event the overall winner became Therese Johaug, who won the third Tour de Ski cup in her career. Natalya Nepryayeva was second and defending champion Ingvild Flugstad Østberg finished third.

Overall leadership
Two main individual classifications were contested in the 2019–20 Tour de Ski, as well as a team competition. The most important was the overall standings, calculated by adding each skier's finishing times on each stage. Time bonuses (time subtracted) were awarded at both sprint stages and at intermediate points during mass start stages. In the sprint stages, the winners were awarded 60 bonus seconds, while on mass start stages the first ten skiers past the intermediate point received from 15 seconds to 1 seconds. The skier with the lowest cumulative time would be the overall winner of the Tour de Ski. For the first time in Tour history, the skier leading the overall standings would wear a yellow bib.

The second competition was the points standings, which replaced the sprint competition from past editions. The skiers who received the highest number of points during the Tour would win the points standings. The points available for each stage finish were determined by the stage's type. The leader was identified by a red bib.

The final competition was a team competition. This was calculated using the finishing times of the best two skiers of both genders per team on each stage; the leading team was the team with the lowest cumulative time.

A total of CHF 560,000, both genders included, was awarded in cash prizes in the race. The overall winners of the Tour de Ski received CHF 55,000, with the second and third placed skiers getting CHF 40,000 and CHF 27,500 respectively. All finishers in the top 20 were awarded money. The holders of the overall and points standings would benefit on each stage they led; the final winners of the points standings would be given CHF 6,000. CHF 3,000 was given to the winners of each stage of the race, with smaller amounts given to places 2 and 3.
