We use seeding to get good rhythm and security in the race, so that everyone can compete with fellow participants who match their abilities. When participants start in a group where they fit in, the tempo is smoother and there is less overtaking, which reduces the risk of accidents. Seeding is only used in some races and it works differently in each case. Read more on the page for the race you are participating in.

We only use seeding in the following races:
  • Vasaloppet (group 0–9)
  • Tjejvasan’s competition class (group 0–2)
  • Tjejvasan’s leisure class (group 3–4)
  • Nattvasan 90. Start groups are based on the finishing time estimated when you make your registration.
  • Nattvasan 45. Start groups are based on the finishing time estimated when you make your registration.
  • Öppet Spår. Start groups are based on the finishing time estimated when you make your registration. Ranking from fastest to slowest estimated results.
  • Other races are leisure races where your start group is assigned after registration.

Vasaloppet 45 is an exception where those registered for Vasaloppet the same year may start in the Vasaloppet group (group 0).

Seeding in Vasaloppet

In Vasaloppet you can seed yourself into groups 0-9. The seeding is based on your earlier performance in our races or on results from another seeding based race. If you have no previous results you will start in group 10. Below you can read more on how it works and which criteria and races apply.

How it works

Participants who have results from Vasaloppet, Öppet Spår, Vasaloppet 45 or Tjejvasan are automatically seeded into the correct start group. For other races you must send in your results. Results are valid for three years. If you get your results to us three weeks before the race, we can guarantee that you will be seeded. After that we cannot guarantee that we will have time. You should therefore check if you have been seeded before arriving for the race. If you have not, you can bring the results list from the race you want to seed from and do it on site.

Using results from previous years results in being moved back one group per year. For example: If you get a result one year that puts you in Vasaloppet’s start group 7 that same year, you can still use that result for seeding the year after. But it will then put you in start group 8, since the result is one year old. Using a two year old result will put you back two groups.

Automatic seeding from seeding based races

For Vasaloppet we can now offer automatic seeding from seeding based races. That means that you don’t need to send in your results to us manually after completing a seeding based race.

This is how it works:

1. Give your Vasa ID when registering for a seeding based race. Your Vasa ID can be found under personal details on My pages, My Account, My profile. If you do not have a Vasa ID, contact the Vasaloppet administration and one will be arranged. (Tip! Write down your Vasa ID for easy access in the future.)

2. The organizers of the seeding based race will send us a results list containing your Vasa ID, full name and finish time. When Vasaloppet has received the results they will be added automatically and you will be moved to a new start group, if the results warrant it.

If the organizers do not use automatic seeding you will be able to mail us your seeding. Use the form below or send your results to seedning@vasaloppet.se
