Hong Kong-based Natalia Watkins does Canada's 160km Yukon Arctic Ultra race

Trudging through the snow, pulling a heavy sled near the Arctic Circle may not seem like a holiday, but for one of the city's busy finance executives, it's paradise.
Natalia Watkins took part in the Yukon Arctic Ultra last month: an arduous 160km foot journey in remote northeastern Canada.
The extreme temperatures alone could kill you; forget having to haul a heavy sled further than the distance from Hong Kong to Guangzhou.
"I love big open spaces, it's such a contrast to Hong Kong. And to be able to travel to remote places that some people might never see - it's a gift," says 42-year-old Watkins.
"You meet some real characters who you would never meet in ordinary life … There's adventure in trying something that you don't know whether you will finish."
