Russian luger Albert Demtschenko has praised the Sanki track in Sochi.
The 42-year-old will be competing in his seventh Winter Olympics in his native country.
"It has been operational for three years now," Olympic.org quotes him as saying. "We've studied it very well.
"At the moment, in my view, it's one of the best in the world, in terms of its design, the logistics, and competition-readiness for the Olympic Games. It's better than the tracks at the six previous Games."
Demtschenko won silver medal at the 2006 Turin Games.
