Kortelopet Elite Waves

The Kortelopet Skate and Classic races each have an elite wave. The Kortelopet Skate Elite Wave is comprised of the top 100 men and 60 women from the 2023 Kortelopet SKATE only; Kortelopet Classic Elite Wave is top 40 men and 30 women from the 2023 Kortelopet CLASSIC only.  Participants qualifying for a Korte Elite Wave will automatically be placed in the Elite Wave wave upon registering. Skiers qualifying for the Elite Wave may register for the race until January 14, 2025.  Elite Wave qualifiers that skied a different technique or did not participate in the 2023 Kortelopet will not be placed in the elite wave, but may request to be put on the Elite Waitlist. Anyone skiing in the 2023 elite wave due to an elite upgrade request will have to make the request again in 2024.  Athletes qualifying for the elite wave, but racing a different distance or technique in 2025, or elite athletes new to the Kortelopet must request to be placed on the Elite Wave waitlist of that race here: Elite Waitlist Application

If you were in the Elite Wave in 2024 as an automatic qualifier based on 2023 results, you will automatically be in the Elite Wave in 2025. If you applied to the Elite Waitlist and were assigned to the Elite Wave in 2024, you will need to reapply to the Elite Waitlist for 2025.

Elite Wave registrations & Elite Waitlist requests close on Tuesday, January 14, 2025 at 11:59 pm CST. Open positions in the Elite Wave will be filled from the waitlist after January 26, 2025.

U20 Wave for Junior Racers

If you are a skier born between February 21, 2005 and February 21, 2012 you will be assigned to start the Kortelopet in the U20 Classic or U20 Skate Waves.   If you are placed in the U20 and are a top skier, please see details in the “Kortelopet Elite Waves” section above for requesting placement in the Elite Wave.

The U20 wave is timed using a gun start– all U20 skiers will receive the same start time in their respective wave.  Official time of U20 skiers that start late will still reflect the U20 gun time.  If you are a junior skier and do not want to ski in the U20 wave contact registration@birkie.com and you will be placed in a wave based on the normal seeding process and your time will start when you cross the start line. U20 skiers not starting in the U20 wave will not be eligible for overall or age group awards.

Wave 70

Cross country skiing is a lifestyle sport that allows people to stay active and healthy into their later years. Each year the Kortelopet provides an opportunity to celebrate this for over one hundred skiers over the age of seventy! We recognize these skiers with a special bib and special wave.

Skiløper - Kortelopet Recognition Program

Like Birkie skiers, Kortelopet skiers are a dedicated bunch!  In honor of a Korte skier’s determination and dedication, there is a well-deserved recognition program!  Skiløper, Norwegian for “skier” (pronounced “Shē-lōp-păh”), began in 2019 and recognizes Kortelopet skiers who reach the milestones of 10, 20, and 30-years.  In addition to the current recognition which includes a Kortelopet 10-year plaque, Skiløper skiers receive a unique bib and deservedly a little swagger for earning it!  Here’s how it works:

  • Skiers are recognized at 10, 20 and 30 years for their Kortelopet accomplishments!
    • Skiløper – Ti (Pronounced “tee” means Ten )
      • Unique bib for 10-19 years
      • Kortelopet 10-year plaque
    • Skiløper -Tjue (Pronounced “tu-a” means Twenty)
      • Unique bib for 20-29 years
      • Kortelopet 20-year plaque
    • Skiløper – Tretti (Pronounced “tre-tee” means thirty)
      • Unique bib for 30+ years
      • Kortelopet 30-year plaque

Congratulations Skiløper – You’ve Earned it!
