PERSELØPET ULTRA
The longest day of the Perseløpet year: marathon, 50 km and 100 km on the same flat, AIMS-measured 2,633 m loop. You run many laps, pass your own aid table every lap, and have family and supporters close by all day.
Registration for 2027 is handled by RaceDays ↗, where current prices and terms are listed. The ultra is not a Norwegian championship in 2027. The schedule is the same as last year: mass start at 08:00, and the course closes at 19:00 after 11 hours.
A different kind of Perseløpet
WHAT'S DIFFERENT?
The regular Perseløpet races are short and fast. The ultra is a whole day on the course, and that changes almost everything.

Questions and answers
ULTRA RULES
The rules below applied in 2026. The current terms for 2027 are in the registration at RaceDays.
Who can enter? Is it a championship?
Anyone can enter. The ultra is not a Norwegian championship in 2027, so there are no nationality or club membership requirements. In 2026 the 100 km was the Norwegian championship.
Can I drop out during the race?
Yes, you can stop at any time. Tell the staff in the finish area and hand in your timing chip so the organisers know you have left the course.
Can I change distance?
In 2026 you could change until 06:30 on race day. Moving to a shorter distance was free, and for a longer distance you paid the difference. You can change your entry under your registration at RaceDays ↗.
What about food and drink during the race?
You bring your own nutrition and put it on your table in the aid station area. There is also a staffed drinks station. See sports nutrition (in Norwegian) for tips on long races.
How can I follow the runners?
Timing is by EQ Timing, with live results that update continuously and are shown on a big screen by the finish area.
How do I get there?
Ås skole is in Eidsvoll, north of Oslo and Oslo Airport Gardermoen. There is free parking right by the start. The map page (in Norwegian) has journey planning by train and bus from Oslo S and Oslo Airport to the venue.
