Ed Leigh reflects on the death of Sarah Burke

Ski Sunday's Ed Leigh reflects on the death of freestyle skier Sarah Burke, the 29-year-old Canadian "pioneer" of the sport who died last week from injuries sustained in a training accident.

Burke helped bring freestyle skiing events to the Winter Olympics, and was considered a gold medal contender for the 2014 Games. She was injured in a superpipe accident at Park City in the US state of Utah on 11 January.
