KRASNAYA POLYANA, Russia — The men’s 15-kilometer mass-start biathlon race at the Sochi Olympics has been postponed until 10 a.m. Monday because of fog.

The race, initially set to start 7 p.m. local time, had been delayed for one hour as organizers said fog at the Laura Cross-Country Ski and Biathlon Center made the visibility too poor on the shooting range.

However, conditions didn’t improve enough to start the race at 8 p.m.

Martin Fourcade of France will be aiming for his third gold medal of the Sochi Olympics, while Ole Einar Bjoerndalen of Norway could win a record 13th Winter Olympic medal.
