The 2010 gold was the first gold for the U.S. in bobsled in 62 years.
"The first gold in 62 years was huge," Holcomb said.
What the world didn't know about Holcomb was that while he was driving, he was suffering from a rare eye disease that left him steering blind.
"I kept it secret," Holcomb said. "Nobody knew about it. I drove by feel. I learned to drive by feel because I was losing my vision."
With his sight failing, Holcomb was struggling with depression and one night he tried to take his own life.
"The signs are there but people are very good at hiding them," Holcomb said. "I was really good at hiding them. We need to get it out that there is hope out there."
Holcomb decided to battle his loss of vision and find a solution. He tried a revolutionary surgery that would be named after him after it worked to correct his vision.
"I ended up having the Holcomb C3R, a procedure that saved my vision" he said.
Now with that challenge behind him, Holcomb comes to Sochi with new sight and he's enjoying the ride.
"It's a fun sport," Holcomb said. "Those two minutes a day is amazing."
Holcomb will compete in the two-man qualifying round on Sunday in Sochi.
