The winter Olympics may now take place in a different year to its summer equivalent but there have been plenty of stars down the years who have left a significant mark on both Games.
The route from athletics champion to bobsleigh medal winner is one that has been incredibly well trodden, making all sorts of history in the Games.
But plenty of athletes have fancied their chance in all sorts of conditions and have produced remarkable results when putting their skills to the test in different sports.
Here, Sportsmail looks at those who have been most successful when competing at both a summer and winter Olympics.

Eddie Eagan
The only Olympic champion to have won gold at both the summer and winter Olympics, Eagan has a unique spot in history, for the time being at least.
While studying at Yale and then Harvard University in America, Eagan developed a passion for boxing, but he would take it a step further at the 1920 Antwerp Games, taking gold in the light-heavyweight division.
But just four years later in Paris he appeared to go from hero to zero when he fell at the first hurdle on his quest to defend his Olympic crown, losing in the first round by Britain's Arthur Clifton.
However, Eagan was thrown a lifeline more than a decade later in 1932 when joined the US bobsleigh team for the winter Olympics in Lake Placid, just three weeks after the Olympic Bobsleigh Committee had put the official call out.
Remarkably, having never ridden a bobsleigh before, Eagan and his team won gold ahead of US II. Despite serving in the war and setting the world record for the fastest circumnavigation of the globe by scheduled airline flights, his golds remain arguably his most well-known achievement.

Eddy Alvarez
Had a couple of results gone his way, Alvarez would have joined his almost namesake Eagan in winning both summer and winter Olympic gold medals.
Having begun skating as early as aged five, he developed a liking for baseball during his teenage years. But when the time came to make a decision between the two, he turned down a full scholarship to college in order to concentrate on his skating.
Nearly eight years ago in Sochi, he failed in all individual events, but would win silver in the 5,000m relay. With that achievement ticked off, he went in pursuit of glory in the other.
Alvarez was selected for the summer Olympic side that went to Tokyo just a few months ago, having excelled for Florida Marlins.
And a Games where he carried the country's flag in the opening ceremony nearly ended in eternal glory, only for the hosts to beat them in the final.

Jacob Tullin Thams
The Norwegian made his own piece of history by becoming the first Olympic ski jumping gold medalist in history in the individual large hill competition at Chamonix 1924.
But four years later in St Moritz, things turned uglier when a dispute broke out over the rules between Swiss athletes and his own team-mates following the first round of jumping.
Thams appeared to take the Swiss' accusations of 'cowardice' to heart, and when anger fills the mind, logical thinking is often found wanting.

A 'normal' jump on his second attempt could have helped him secure another possible Olympic gold, but instead Thams opted to jump a record 73 metres, and while he flew that distance he was disqualified for falling and finished 28th.
Most would have called it a day, but not Thams. In 1936, he returned to the fray but in the Berlin Games in the summer as part of the Norwegian sailing team in the eight-metre event.
A silver medal would follow, consequently becoming just the second athlete in history to win medals at both summer and winter Games.
Christa Luding-Rothenburger
Representing East Germany in the 1980s, she is the only one of the six athletes to win medals in both the summer and winter Olympics in the same calendar year.
Luding-Rothenburger realised her Olympic dream by winning gold in the 500m speed skating event in Sarajevo, and most would have been satisfied with that.
But her then coach - and later husband after he achievements in 1988 - Ernst Luding, advised her to take up cycling to keep fit during the summer months, and during this period her second sporting talent grew.

Her focus failed to drift from speed skating though, winning the silver in the same event in the 500m and the gold the 1,000m event four years later in Calgary.
And she vindicated the president of the East German sports federation's decision to allow her to enter international cycling competitions that same year, picking up a silver medal in the match sprint cycling event in Seoul.
A bronze medal in speed skating would also come at the 1992 Winter Games in Albertville, this time competing for a reunified Germany, but her proudest moments in 1988 will never be broken now that the games take place in different years.
After winning the speed skating event in Sarajevo, she would later triumph in Seoul in cycling
Clara Hughes
Only six people have won medals at the summer and winter Olympics, and just one has won multiple medals at both Games.
Clara Hughes was seemingly rescued from a life of smoking, drinking and drugs by speed skating, which inspired her after she watched the 1988 Games. But just 12 months later she had dropped it for cycling.
Two bronzes at the Atlanta Olympics in 1996 in the road race and the time trial vindicated her decision somewhat, especially as Hughes also became the first Canadian woman to win an Olympic medal in the
