In 2020 it will be 500 years since Gustav Vasa's adventure in Dalarna, 1520–21, and 98 years since the first Vasaloppet in 1922. This last decade Vasaloppet has seen the number of registered participants double! These past five years we've been able to celebrate getting close to 100,000 participants, though that magic number hasn't been reached yet. Vasaloppet can now proudly introduce the Vasaloppet year 2020 with more challenges and races than ever to choose from. Registration for Vasaloppet's Summer Week 2020 opens on Sunday, September 15.
