When: Feb. 8.
Best of the U.S.: Jonathan Kuck didn't finish lower than eighth this season.
Best of the rest: World record-holder Sven Kramer of the Netherlands, the sport's top long-distance skater, won gold in 2010 and silver in 2006.
U.S. chances to medal: After Kuck, distant hope rests on first-time Olympians Patrick Meek, 29, and Emery Lehman, 17.
Little-known fact: Lehman wears stock boots that cost about one-tenth the price of custom skates most Olympians wear.
