When: Feb. 9, 7.5k sprint; Feb. 11, 10k pursuit; Feb. 14, individual 15k; Feb. 17, 12.5k mass start; Feb. 19, mixed relay (men 2-x-7.5km/women 2-x-6k); Feb. 21, 4-x-6k relay.
Best of the U.S. women: Susan Dunklee's recent fourth in a World Cup race was the highest finish by a U.S. woman on the circuit since 1994. Twins Tracy and Lanny Barnes touched hearts when Tracy gave up her place on the U.S. team for Lanny, who had been sick at the final qualifying event. Both had competed at the 2006 Games, Lanny again in 2010.
Best of the rest: Darya Domracheva is shooting (and skiing) to become Belarus' first female Winter Olympic champion, while Gabriela Soukalova has a good chance of winning the Czech Republic's first biathlon medal. Norway's Tora Berger, gold medalist in 2010, swept the season titles on the 2013 World Cup circuit.
U.S. medal chances: Best U.S. individual women's finish was a 14th in 1994. Another top-15 effort is a reasonable goal.
Little-known fact: Germany's Andrea Henkel, winner of four Olympic medals, including two gold, is Tim Burke's longtime girlfriend. Henkel, 36, intends to retire this season and live with Burke in upstate New York.
