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 and a finisher pin, 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
      • Listed in the results of the Birch Scroll as a Skiløper – Ti
    • Skiløper -Tjue (Pronounced “tu-a” means Twenty)
      • Unique bib for 20-29 years
      • Listed in the results of the Birch Scroll as a Skiløper – Tjue
    • Skiløper – Tretti (Pronounced “tre-tee” means thirty)
      • Unique bib for 30+ years
      • Listed in the results of the Birch Scroll as a Skiløper – Tretti

If you’ve skied 10 or more Kortelopet races, you’ll automatically receive a bib for the next year for your overall Korte accomplishments as a Skiløper (Ti, Tjue, or Tretti!).

Congratulations Skiløper – You’ve Earned it!

Wave Placement

The American Birkebeiner Ski Foundation utilizes a seeded start structure for four of its events:  Birkebeiner Skate, Birkebeiner Classic, Kortelopet Skate, and Kortelopet Classic.  Participants are seeded into start waves based on their race history.  The first priority for wave placement is your best result from 2018 – 2020 Korte events for the same event for which you are registering- distance and technique (see the Wave Seeding Criteria tables below).

If you do not have a finish time for that specific event (same distance & technique) from 2018 -2020, but do have a finish time from any of the other distances/techniques, you will be placed in a wave based on the best finish result from that event, plus or minus an adjustment factor which accounts for the historical difference in the strength of competition between the races (see the Event Adjustment Factor table below).  If you have participated in multiple Birkie events in 2018-2020, wave placement criteria will use results from the similar distance race, then from a similar technique.  Race times from the 2021 Kortelopet race will not be used for calculating 2022 wave placement.

Participants who do not have a Korte event finish time from those years will be placed in the last wave.  The goal of wave placement is to place participants of similar abilities together to minimize passing and encourage a smooth flowing race.

The Korte has three special waves- Elite, U20 and Wave 70, for younger and older skiers. See the details for these waves below.

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 50 women from the 2020 Kortelopet Skate Race only; Kortelopet Classic Elite Wave is top 40 men and 20 women from the 2020 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 26, 2021.  Elite Wave qualifiers that skied a different technique or did not participate in the 2020 Kortelopet will not be placed in the elite wave, but may request to be put on the Elite Waitlist. Athletes racing a different technique in 2021 or elite athletes new to the Kortelopet must request to be placed on the Elite Wave Waitlist by emailing  Emails should include a race resume or qualifications.

In 2021, Korte Champions will be crowned on Saturday for skate and Sunday for classic.  Elite skiers must race on those days to be eligible for awards.

All elite wave qualifiers for 2021 will be automatically qualified in 2022.  Anyone skiing in the 2021 elite wave due to an elite upgrade request will have to make the request again in 2022.

Elite Wave registrations & Elite Waitlist requests close on January 26, 2021 at 4:00 pm CST. Open positions in the Elite Wave will be filled from the waitlist after January 26, 2021.

U20 Wave for Junior Racers

If you are a skier born between January 1, 2001 and February 25, 2008 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 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.

Event/Technique Change Request

Participants may request to change from the Korte to the Birkie or Prince Haakon and/or change technique between Skate and Classic at any time until 4:00pm CST on January 19, 2021.  Wave placement is subject to availability at time of request. If the wave that you qualify for is full, you will be assigned to the next wave with space available. (Participants may no longer transfer from the Korte to the Birkie once the Birkie is full.)  A change fee of $25 will be applied. You will receive an updated e-mail confirmation reflecting the change once the change has been made. If you do NOT receive an updated e-mail confirmation within 10 business days, contact

Click here to request an Event/Technique change.

Wave Upgrade Request

Participants may utilize their result from the list of qualifier competitions to improve on their placement from the above criteria. Similar to the comparison between the American Birkebeiner events, the results of the qualifiers will be adjusted based on the strength of competition, distance, and course elevation profile.

Click here to make a wave upgrade request by 4:00pm CST on January 19, 2021. All requests will be charged a $15 service fee, whether a wave upgrade is granted or not. Wave upgrades are subject to availability, if the wave that you qualify for is full, you will be assigned to the next wave with space available. You will receive an updated wave placement email confirmation if an upgrade has been made. If you do NOT receive an updated e-mail confirmation within 10 business days, contact  In an effort to create an environment with reduced on-trail passing, consistent race flow, reduced congestion in aid stations, and the safest possible environment for all skiers, we are unable to downgrade a skier to a wave that is slower than the wave they qualify for (and outside of the wave options provided in the Race Day Selection emails).

You may request to use a race result from the list of qualifier competitions to improve your wave placement. Follow these steps to see if you are eligible for an upgrade:

  1. Determine your percent back in the qualifier race. Take the Difference in time between You and the Winner. Divide that by the Winner’s time. (Example: your time is 2:36, winning time is 2:00; Difference =36 minutes/2 hours = 0.3 x 100 = 30% back)
  2. Determine your Percent Back Equivalency (PBE). Add the qualifier race’s Adjustment Factor, which is found on the Qualifier List. PBE = Your % Back + Adjustment Factor (Example your 30% back + 57% Adjustment Factor = 87% Back Equivalency.)
  3. Determine where your Percent Back Equivalency (PBE) would place you. Look up your PBE in the 2020 column of the Wave Seeding Table of the race for which you are registered. (Example: A PBE of 87% will place you in Wave 5 for Birkie Skate or Wave 2 for Birkie Classic or Wave 3 Korte Skate or Wave 1 Korte Classic)

Request an upgrade only if your PBE will place you in a lower wave.  Make sure you have completed steps 1-3 before submitting your request as there are no refunds.
