Fog postpones men's biathlon
The men's biathlon 15km mass start fell victim to the weather on Sunday night, making the event the first to be called off at the in Sochi.
Sudden fog descended upon the Laura Cross Country Skiing and Biathlon Centre, forcing tournament organisers to delay the event by one hour to a 2000 start local time (1600GMT).
But conditions did not improve and it was decided the race would take place on Monday, with a start time still to be arranged.
Ole Einar Bjoerndalen can become the most decorated Winter Olympian in history if he wins his 13th medal on Monday.
However, the 40-year-old Norwegian, gold medallist in the 10km sprint last weekend, will face stiff competition from France's Martin Fourcade, who is looking for a hat-trick of titles in Russia after triumphing in the individual and pursuit events.
It is the heat that has caused the most consternation since the beginning of the Games, with a couple of alpine events starting earlier than the designated start time, while British cross country skiers Andrew Musgrave and Andrew Young bemoaned the temperatures that forced them to contest the 15km classical race in T-shirts and stop at drinking stations.
