Biathletes have seen their daily rhythm at the Sochi Games disturbed by the rescheduling of a race — a race that then didn't go ahead as planned.

Unlike most World Cup events, all biathlon races at the Olympics are scheduled in the evening. Many competitors are sticking to a Western or Central European time schedule, ignoring the fact that Sochi is three hours ahead of the places where they usually compete during the World Cup season.

That means, they go to bed late and sleep until halfway through the morning.

Not so on Monday.

Thick fog the night before had forced organizers to postpone the men's 15-kilometer mass start until Monday morning, 10 a.m. local time, disallowing the athletes to sleep in.

"This will definitely be the earliest wake up in Sochi so far!" U.S. biathlete Tim Burke from Lake Placid, NY, posted on Twitter.

However, getting up early proved to be useless. Fog was still hanging over the Laura biathlon venue, leaving organizers no option but to further postpone the race by at least 5 1/2 hours until 3.30 p.m.

"Hurry up and wait. The race is again delayed because of fog. Back to bed for me!" Burke tweeted this time.

Two-time gold medalist Martin Fourcade, a favorite for the race, also commented on Twitter on his Olympic daily routine being interrupted.

"Don't thank me for getting up at 7am for nothing!" the Frenchman tweeted.
