Vasaloppet is an annual cross-country skiing competition in Sweden that started off in 1922. Nowadays it is held the first Sunday in March each year.
The competition runs from Sälen to Mora. Women were banned from participating between 1924 and 1980, due to the length of the race (90 kilometers). In 1997, an official women's award was established.
The race is held to commemorate the historical events related to Gustav Vasa back in the early 1520's.
