Tara Parker-Pope, The New York Times:
A typical elite cross-country skier will burn about 30 calories a minute during training — by comparison, a 155-pound person on an elliptical machine burns about 11 calories a minute.
Research has shown that a typical male elite cross-country skier must consume 7,000 to 8,000 calories a day — more than three times the caloric needs of an average male — to meet the energy demands of the sport. Female elite skiers must eat about 3,500 to 4,000 calories a day — about double the calories consumed by the average woman. (A Swedish study found that during the hardest training days it can reach 8,126 for men and 4,780 for women — about double the calorie needs of Kenyan marathon runners.)
What does it take to consume 8,000 calories — the equivalent of about 20 plates of lasagna or 40 scoops of ice cream — every day?
Canada’s Northwest Passage is seeing an increase in traffic. The French explorer hopes to raise awareness to the risks of environmental damage posed by the increased shipping activity and climate change.
Levon Sevunts, writing for Radio Canada International:
French explorer Alban Michon plans a solo skiing and diving expedition along part of the fabled Northwest Passage in the Canadian Arctic Archipelago to raise awareness of risks facing the fragile northern environment due to climate change.
The Northwest Passage or rather the passages (there are several possible routes through the archipelago) connects the Atlantic and Pacific oceans and has become increasingly ice-free during summer months, attracting a growing number of ships taking the polar shortcut.
The 2017 was a busy shipping season in the Canadian Arctic that saw 31 complete and 14 partial transits through the Northwest Passage.
