Four years ago in Vancouver, American speedskater J.R. Celski won the bronze in the 1,500-meter competition. He'll be looking to improve on that in Sochi, but he'll be facing a formidable foe.

Russia's Viktor Ahn missed the Vancouver Games because of a knee injury. But in 2006, when he competed for his native South Korea as Ahn Hyun-Soo and was competing for his, he won three gold medals.

Kind of crazy … but then so is speedskating.
