Time-sensitive — start this plan now
With Birkebeinerrittet in mid-August 2026, you should start week 1 of this 16-week plan now (June 2026) to peak on race day.
16-week periodisation plan
Phase 1: Base (Weeks 1–4)
4–6 hours/weekBuild aerobic cycling base
3–4 MTB rides per week. Focus on long rides at easy to moderate pace. Begin with 2–3 hour weekend long rides. No backpack yet — work on technical bike handling in terrain. Cycling-specific strength training (squats, Bulgarian split squats) 2×/week.
Phase 2: Climbing Strength (Weeks 5–8)
6–8 hours/weekIntroduce hill intervals
1 hill interval session per week (4–6×5 min hard efforts uphill). Long ride extends to 3.5–4 hours. Introduce backpack at 2–3 kg on long rides — gradually increase toward 3.5 kg. Test hydration system and mid-ride nutrition.
Phase 3: Race-Specific Fitness (Weeks 9–12)
8–10 hours/weekRace-specific loads
Long rides 4.5–5 hours with full 3.5 kg pack in Birkebeiner-like terrain. Simulate the elevation profile: 1–2 sustained climbs (20–30 min) per ride. One tempo session per week (45–60 min above threshold). Focus on eating and drinking while moving.
Peak Week (Week 13)
10–11 hoursLongest ride
Longest ride of the plan (5–5.5 hours with pack). Include a full day in Birkebeiner-like terrain. After peak week, taper begins.
Taper (Weeks 14–15)
5–6 / 3–4 hoursMaintain fitness, reduce fatigue
Week 14: Reduce volume 30–40%. Keep intensity in hill session. Long ride 2.5–3 hours with pack. Week 15: Reduce further. 2–3 rides of 60–90 min. No hard efforts. Check and prepare bike and gear.
Race Week (Week 16)
Light activationRest and preparation
2 short rides (30–45 min easy spin Monday/Wednesday). Thursday–Friday: rest. Saturday is Birkebeinerrittet. Pack your backpack the day before, eat familiar foods, sleep early. Transport to Rena starts early morning on race day.
Nutrition and hydration
Before the race
Breakfast 3–4 hours before start: porridge with banana, nut butter, and a little salt. Avoid fat and fibre. Drink 500ml water upon waking.
During the race (every 30–45 min)
Energy gel, dates, or cycling bar. Drink 500–750ml per hour (more in heat). Feed stations are placed along the course.
Salt and electrolytes
Take salt tablets every 60–90 min in warm conditions. 88km = 3–7 hours sweating = significant salt loss.
Food in the pack
Carry enough food for the entire race in your backpack — stop at feed stations only to refill water and adjust.

FAQ
What are the prerequisites for this training plan?
The plan is designed for experienced cyclists who already have a solid aerobic base. You should be able to ride 2–2.5 hours in terrain without becoming exhausted. Initial weekly volume is 4–6 hours on the bike. If you're new to mountain biking, we recommend starting with a shorter Norwegian cycling event (e.g. Tryvann Rundt, approx. 13km) and building from there.
Do I need a mountain bike or will a gravel bike work?
Birkebeinerrittet requires a mountain bike. Gravel bikes and road bikes are not permitted on the official course. You need a hardtail or full-suspension MTB with 29" wheels, 2.0–2.35" tyres, and hydraulic disc brakes. See our bike requirements page for detailed gear recommendations.
How much elevation gain are we training for?
Birkebeinerrittet has approximately 1,950 metres of elevation gain over 88km. The hardest climbing is in the first 25–30km up to the Sjusjøen plateau. The training plan introduces hill intervals in phase 2 and gradually builds to sustained climbing segments in phase 3. If you don't have Birkebeiner-like terrain nearby, you can supplement with rollerskiing or high-resistance spinning sessions to simulate the climbing load.
What weight should my training backpack be?
Train progressively toward 3.5kg pack weight. Start with 2kg from week 5, increase to 3kg in weeks 7–8, and reach 3.5kg by week 9 at the latest. Note that 3.5kg is the minimum requirement — your pack will realistically weigh more with water, food, and tools. A good hydration pack (2–3 litres) with food and emergency gear is typically 4–5kg. Test the pack thoroughly in training well before race day.
