Laura

Sports: Biathlon, cross-country skiing
Capacity: 15,000 (7,500 each for biathlon and cross-country)


Both biathlon and cross-country sports have their own start and finish areas and warm-up zones. The centre shares the name of the nearby Laura River which, in turn, was named after a local legend: Laura was a young woman who jumped into the river's turbulent current rather than live with a prince she did not love.
