How many calories does biathlon burn?

Competition biathlon can burn 700–1,400 kcal per hour including shooting phases due to its extreme skiing intensity (MET 13.5). Training sessions are more moderate at 500–900 kcal/h.

Why is biathlon one of the highest-calorie sports?

Biathlon combines sustained cross-country skiing (one of the most demanding endurance activities) with the physiological stress of transitioning to precision shooting under fatigue.

Does cold weather really increase calorie burn?

Yes. The body expends additional energy for thermoregulation in cold conditions. Research suggests a 5–15% increase depending on temperature, wind, and clothing.

Key Takeaways

The 2024 Compendium assigns competition biathlon (skating technique) a MET of 13.5 — among the highest for any sport.^[1]
Biathlon uniquely combines sustained high-intensity skiing (70–90% HRmax) with precision shooting phases at lower heart rates.^[2]
Cold weather can increase energy expenditure by an additional 5–15% through thermoregulation.^[3]

How the Calculation Works

The calculator separates skiing and shooting phases, each with its own MET value:

skiKcal = skiMET × weight(kg) × skiHours

shootKcal = 2.0 × weight(kg) × shootHours

total = skiKcal + shootKcal

For related winter sports, see the Skiing Calculator or the Snowshoeing Calculator.

Limitations and Important Notes

Competition MET values may overestimate training-pace energy expenditure.
The cold weather surcharge is an approximation; actual thermoregulatory cost depends on clothing, wind chill, and acclimatization.
