About Birkebeinerløpet
Birkebeinerløpet is the trail running variant in the Birkebeiner family — the same inspiring tradition as the cycling race (88km) and the ski race (54km), but on foot. 21km from Rena to Lillehammer through forest and mountain terrain, with approximately 1,000 metres of elevation and the mandatory 3.5 kg backpack.
The run is typically held the same weekend as Birkebeinerrittet (cycling) in mid-August. This gives the opportunity to combine both — cycling race on Saturday, run on Sunday — for the especially ambitious!
13-week training plan
Weeks 1–4: Running base
Build to 4 runs per week (25–35 km total). Focus on long easy runs at comfortable pace. Begin carrying backpack with 1–2 kg on one run per week.
Weeks 5–8: Climbing strength
Introduce hill intervals once per week (6–8×1 min hard uphill). Long run extends to 14–16 km on trails. Train with 3 kg pack on long runs. Lower body strength (squats, lunges) 2×/week.
Weeks 9–11: Race-specific fitness
Long run 16–18 km on trails with 3.5 kg pack. Tempo run 30–40 min. Focus on eating and drinking while moving. Simulate the course if possible (hilly forest terrain).
Week 12: Taper
Reduce volume 40–50%. Keep 1 hill session and 1 long run (12 km). Ensure good recovery and rest.
Week 13: Race week
2 short runs (20–30 min) Monday and Wednesday. Thursday–Friday: rest. Pack backpack with familiar food and gear. Race day: eat early breakfast, start at steady pace.

FAQ
What is Birkebeinerløpet?
Birkebeinerløpet is a 21km trail run (half marathon+) organised by Birkebeiner Nordic Race AS, typically the same weekend as Birkebeinerrittet (cycling) in mid-August. The race runs from Rena to Lillehammer through forest terrain, with approximately 1,000 metres of elevation gain. Like all Birkebeiner events, participants are required to carry a backpack weighing at least 3.5 kg — a tribute to the historical Birkebeiner warriors' journey in 1206.
Is Birkebeinerløpet the same as Birkebeinerrittet?
No — they are two separate events within the Birkebeiner family. Birkebeinerrittet is an 88km mountain bike race. Birkebeinerløpet is a 21km trail run on foot. Both are typically held in mid-August, and both require the 3.5 kg mandatory backpack. Birkebeinerrennet is a third event — a 54km cross-country ski race held in winter (typically late March).
What is the mandatory backpack in Birkebeinerløpet?
All Birkebeiner participants must carry a backpack weighing at least 3.5 kg. The pack is checked at the start. You fill the pack with a hydration bladder, food, emergency gear, and possibly extra clothing to reach the weight requirement. A 1.5–2 litre bladder with water + food + emergency kit is typically enough to reach 3.5 kg. Train with the pack in the weeks before the race to get used to the weight and find a pack that fits without chafing.
What is the average finishing time?
Average finishing time for Birkebeinerløpet is approximately 2–3 hours depending on fitness and trail experience. The elite finishes in around 1.5 hours. For recreational runners with a solid half marathon time, we recommend targeting 2.5 hours as a starting point. Note that the backpack and terrain profile make this significantly harder than a flat road half marathon — add 20–30 minutes compared to your typical half marathon time.
