The Olympic events will be split between the mountain resort of Krasnaya Polyana and a purpose-built Olympic Park in the city, connected by a 45-minute high-speed train line.
As with any major project, there have been problems.
Human Rights Watch put out a report the day before the "year to go" milestone claiming that workers have been exploited by the construction companies. CNN contacted organizers for comment but has not received a response.
Last year's high-profile alpine skiing test event -- the Winter Olympics' glamor sport -- was marred by criticisms of the course.
"They're pretty inexperienced there, they never held the World Cup so it was really rough and really hard," three-time Olympic silver medalist Ivica Kostelic told CNN's Alpine Edge show.
"We had huge jumps and after three days of training, I went for a slalom combined run and I'm skiing down and I feel like something popped in my knee like 'crack' and I didn't feel any pain so I just carried on skiing, but later I found out that my meniscus was broken."
Despite such concerns, most skiers have come out in favor of the venue, designed by former skiing great Bernhard Russi.
"The hill itself is amazing but the way they set the course last year was not ideal," says U.S. Olympic hopeful Travis Ganong.
"I think they learned a lot from that World Cup and I think they'll open up the course a little bit and make it more like a downhill. It was very turny and a lot of guys didn't like that.
"They didn't ask for feedback but they heard a lot of it from racers and the coaches, and I think they're listening, so hopefully we'll have a more open, faster downhill set for the Olympics."
Ganong says North American skiers might find Sochi more familiar than their European counterparts.
"In the Alps they don't get the same kind of snow. Sochi has the mountains like you get in the Alps but the snow that you get in the U.S. and Canada -- it's pretty amazing," he says.
"The downhill course is very challenging and it demands the best skier in the world to perform on that day to win. I don't think you'll see some unknown people doing well, at least in the downhill. It'll take solid skiing from a very good skier to win."
Sports mad president
Winning medals is also among the top goals for Russia's sports-mad president, who attended a figure skating test event in Sochi in December.
"It was exciting," says American skater Charlie White, who won the Sochi Grand Prix Final with his dance partner Meryl Davis.
"We had heard reports all week that he was there, not there, so in our five-minute warm-up we heard loud applause and we were able to glance up at the videotron at the top and saw that the video was on him.
"It's a big deal to be able to perform for such an important figure. It's great that he cares to come and watch. I can't imagine how nervous I'd be in front of President Obama."
White and Davis won silver at Vancouver, and the 2011 world champions are coached by Russian Marina Zueva.
