In Sochi, Russia, Steve Holcomb is attempting to drive the United States to another gold medal in bobsled in both the two-man and four-man events.
Along the way, Holcomb has battled both depression and a degenerative eye disease to become the driver to beat.
"We've got to defend the gold medal in four-man," Holcomb said. "That's one of our biggest goals. It was the first gold in 62 years, which was huge."
The medal in Vancouver was a defining moment for the United States, and the time between medals showed how many variables can affect a bobsled run.
"For us, every single piece is crucial," Holcomb said. "If you don't have a good start, you're behind. There's no accelerating, you can't catch up."
The degenerative eye disease Holcomb battles is something that affected his duties as a driver to the point where he opened up about the struggles.
"I learned to drive by feel because I was losing my vision," Holcomb said. "If I crashed and hurt somebody, I'd never be able to live with myself, especially if I kept it a secret."
Fortunately, Holcomb's vision was saved with a surgery that now bears his name.
"I ended up having the Holcomb C3-R, a procedure that saved my vision," he stated. "It was renamed the Holcomb C3-R. It was quite an honor to name the procedure after me."
While Holcomb competes in both two-man and four-man bobsled, the four-man team has a claim to fame in its "Night Train" sled.
"It's a very intimidating sled. It's a very intimidating name," he said. "It came out with that flat black sled with the night train logo and it was fast. It dominated the hill, and that sent shivers down everybody's spine."%3Cimg%20src%3D%22http%3A//beacon.deseretconnect.com/beacon.gif%3Fcid%3D146089%26pid%3D46%22%20/%3E
