A gross estimate using about 1.04 kcal per kilogram per kilometre. Real burn shifts with terrain, fitness, and running economy.
Does pace change the calories?
Less than most people think. The energy cost of running comes mostly from moving your body weight a set distance, so a slow 10K and a fast 10K burn roughly the same total. Going faster burns more per minute, but you finish sooner, and it mostly evens out.
