Ultravasan is an annual ultramarathon and trail run in Sweden, which was hosted for the first time in 2014 following the route of the ski race Vasaloppet. The 90 km race is the largest ultramarathon race in Sweden, and attracts more participants than the 45 km event.
The race is arranged on two distances:
The races are part of the Vasaloppet Summer Week, along with the bike races CykelVasan and the shorter running races TrailVasan.
Jonas Buud was involved in the creation of the race, and won the first two editions of Ultravasan 90. His time in 2015 is still held as the course record, although the course is now longer.
In 2019, Jim Walmsley tried to break Buud's record time, but fell two minutes short.
In 2024, Norwegian former crosscountry skier Laila Kveli won Ultravasan 90 and became the first athlete to win both the skiing race and the running race.
In 2025, Olle Meijer took the lead with one kilometer to go and won for the third year in a row. He became the first man to win Ultravasan 90 three times, and the second person to do so after Alexandra Morozova.
Also in 2025, Agnes Josefsson won Ultravasan 45 at only 19 years of age, setting a course record in the process.
