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 in 2025 based on your best result from 2020, 2022, and 2023 Birkie events (see the Wave Seeding Criteria tables below). 2024 results are not eligible for consideration.  If you’ve completed multiple events, the Event Adjustment Factor table accounts for the historical difference in the strength of competition between the races. (Take your Percent Back from event winner +/- the applicable Adjustment Factor. See a sample calculation under “Wave Upgrade Request.”).

While 2021 and 2024 Birkie and Open Track times will not count towards placement, race completion (in-person or virtual) will be applied according to tables below.

Participants who have never completed an American Birkebeiner, Kortelopet, or Prince Haakon event 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.

If you do not receive a wave placement e-mail within 14 business days, please contact registration@birkie.com.

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

Wave Upgrade Request

Participants may utilize their result from this 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.

  • All requests will be charged a $25 service fee, whether a wave upgrade is granted or not. To request a wave upgrade by 11:59pm CST on January 14, 2025 (subject to availability):
    • Login to your RunSignUp profile.
    • Scroll down to your event and click ‘Manage Registration’
    • Click ‘Add Ons’ (along either top or bottom menu)
    • Make appropriate change to your “Wave Upgrade Request” section

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 14 business days, contact registration@birkie.com.  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 Overall Winner. Divide that by the Overall 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 year column of the Wave Seeding Table of the race for which you are registered. (Example: A 2022 PBE of 87% will place you in Wave 4 for Birkie Skate or Wave 3 for Birkie Classic or Wave 2 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.

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.

Event/Technique Change Request

Participants may request to change from the Kortelopet to the American Birkebeiner, Prince Haakon, or Open Track events or change technique between Skate and Classic until 11:59pm CST on January 14, 2025 unless an event is full (see allowed transfers below).  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 Kortelopet to the American Birkebeiner once the American Birkebeiner 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 approved. If you do NOT receive an updated e-mail confirmation within 10 business days, contact registration@birkie.com.

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!
