speed skating

Speedskating is the U.S.'s most successful winter Olympic Sport. In Sochi this year, great things are expected again.

The secret to their success includes talent, skill and hard work, but there's also a network of support that buoys the team.

Two-time gold medalist Shani Davis is looking to win a history-making third: He would be the first speedskater to win the same event in three different Olympics.
