Cross-Country Skiing Burns More. Burning about 381 calories in 60 minutes of snowboarding provides a slower caloric burn than some other forms of winter exercise. A 160-pound person burns about 533 calories in an hour of slow-paced cross-country skiing and about 419 calories in 60 minutes of light ice skating. The caloric burn from light snowboarding is equivalent to that of light downhill skiing. Related Reading: How to Estimate the Total Calories You Burned While Running.
Serious ski racers go to ski practice daily and have ski races every week. They may also be on a high school ski team if it is available in their area. These ski racers invest in ski equipment including two to three pairs of skis, helmet, Giant Slalom Suit, ski poles with wrist guards, shin guards, and other ski racing gear and equipment. Ski racing equipment can be very expensive, but a serious ski racer skis so often that it is worth it. Serious ski racers are competitive and may strive to become a professional ski racer one day. Recreational ski racers are those skiers that ski once in awhile or just for fun a couple times a month or week.
