Skiing - cross-country, uphill (maximum)

This activity burns approximately 1,085 calories per hour

Compared to skiing on the flat, cross-country skiing uphill expends significantly more calories. How much energy a skier uses depends on the grade of the hill, its length, the skier's body weight and the skiing pace. Skiing uphill can easily exceed 3 to 4 times the energy requirement of skiing on the flat.
