Birkebeinerrennet has announced a reduction in the mandatory backpack weight, lowering the requirement from 3.5kg to 2kg ahead of the coming editions of the iconic Norwegian long-distance race.

The backpack has been a central element of Birkebeinerrennet since its first edition in 1932, symbolizing the young prince Haakon Haakonsson who was carried over the mountain in 1206. But it has also always served a practical safety purpose.

“The backpack has primarily been – and still is – about safety over the mountain,” said Jostein Buraas, CEO of Birken, in a press release, and added:

“Participants must bring what they need to stay safe if weather and conditions change, or if they get injured.”

The original weight requirement, set when the event launched, was 5.5kg. That figure was calculated after organizers visited a Lillehammer sports store in 1932 to determine what equipment participants should carry over the mountain. In 1993, the requirement was reduced to 3.5kg to reflect lighter, more functional gear available at the time.

Now, more than three decades later, the rapid development of modern technical textiles has prompted a further update. Clothing, shells, and safety equipment have all become significantly lighter while offering the same or greater protection.

“The most important thing has never been the weight itself. The most important thing is that the participants have the necessary equipment over the mountain,” said Buraas.

The new 2kg requirement takes effect from the upcoming events and also applies to this year’s Birkebeinerrittet. The backpack remains a mandatory part of the race.

“It will still be there over the mountain – both for safety and as a symbol of our history,” said Buraas.
