Thursday sees the 'unofficial' start of the Winter Olympics in Sochi 24 hours before the opening ceremony takes place.
No medals are on offer as the programme sees only a handful of qualification events take place before the real thing gets underway.
The first to get going is a new event for the Games, snowboarding's 'slopestyle' category, where athletes perform on a slope featuring various forms of obstacles (rails, quarterpipes, and jumps).
The competition is formatted in an elimination system with semi-finals and finals, with two runs in each round.
British interest centres on Billy Morgan and Jamie Nicholls in the men's, while Jenny Jones goes in the women's.
Another discipline new to these Olympics - team figure skating - also gets underway. Scores from performances in men's, women's pairs and ice dance are added to give each six-athlete team an overall score.
The team men's short programme precedes that of the team pairs. Stacey Kemp and David King are the British pairs entry, while Matthew Parr has a place on the team event but not the individual later in the Games.
The final event on the first day is qualifying in the women's moguls skiing.
