Hotels have been quick to cash in with some of those near to the start in Sälen charging 2,000 kronor a night.
Mora council commissioner Peter Helander told Radio Sweden that the main reason for the boom in visitors in the past two years has been down to the weather.
"We can see that if there is snow this year we will have a big number applying for next year and then it seems that people are actually trying to exercise."
The first race in Vasaloppet week, last sunday's non competitive open track race saw 6,000 skiers leave Sälen for the 90 kilometre journey to the finish line in Mora. At one time the vasaloppet was just the one race but now the event has spread to 9 different races over 7 days.
In two decades, it's gone from a little under 20,000 taking part during the week to 57,500 last year. If the figure continues to grow then race organisers say they will have to set a maximum ceiling of numbers taking part.
It's not just Vasaloppet week which has taken off, more Swedes than ever before are taking to their cross country skies or buying a pair for the first time.
Figures from TT news show that three 3 years ago, sales of cross country skies were at the 70,000 mark, last winter that figure had jumped to 120,000.
