So what would it be like to actually ride the luge track that's featured in the Olympics this year? Check out this video for the POV - at the end it's about 90 mph...
Then watch as Tony Benshoof explains each curve of the track. Tony came in 8th (and the best for the US team) in this year's Men's Luge.
And here's my favorite POV video from the track.
Women's Luge starts tonight at 8pm. And they'll start even further down the track that the men. The men have now been starting just before curve 3. The women will start just before curve 6 - that's usually the start point for people that are learning to luge.
