Sochi now in critical prep period
IOC President Thomas Bach says Russian organizers of the Winter Olympics in Sochi should brace themselves for the toughest preparation period ahead.
Sochi marked the 100-day countdown to the games on Tuesday night.
Bach says ''these 100 days will be the toughest ones in the preparations.''
Bach, who toured Olympic venues with Russian President Vladimir Putin on Tuesday, told a group of Sochi volunteers that ''what you have achieved so far is really fantastic.''
Russia is spending $51 billion to deliver the games, making it the most expensive Olympics in history.
The games will take place from Feb. 7-23.
