The International Skating Union (ISU) Nebelhorn Trophy begins in Oberstdorf tomorrow as figure skaters aim to secure the final qualification spots for the Pyeongchang 2018 Winter Olympic Games.

More than 100 skaters and couples will compete for six spots in the men’s and women’s competitions, four in the pairs and five in the ice dance in South Korea in February.

As hosts, South Korea are guaranteed an extra spot per discipline if they do not make it through the normal qualifying procedure of the World Figure Skating Championships and the Nebelhorn Trophy.

Additional quota places may become available in case countries do not use all their spots and therefore give them back.

The event could also see North Korean athletes secure their place at Pyeongchang.

The country's participation at the Olympics is in doubt, however, amid wider tensions on the Korean peninsula and they have not yet qualified any athlete.

Among the top contenders for an Olympic spot are the reigning world junior pairs champions Ekaterina Alexandrovskaya and Harley Windsor of Australia as well as the 2016 world junior pairs champions Anna Duskova and Martin Bidar of the Czech Republic.

So far 24 ISU Members have earned quota places for Pyeongchang 2018 at this year's World Figure Skating Championships in Helsinki.

In the Finnish capital, 24 places were up for grabs in the men's and women's competitions, 16 in the pairs and 19 in the ice dance.

Nations that have already earned quota places at the World Championships cannot gain additional spots in Oberstdorf.

However, some skaters from qualified countries can take part outside the qualification process and use the Nebelhorn Trophy as preparation for Pyeongchang 2018.

World Championships pairs silver medallists Aliona Savchenko and Bruno Massot of Germany will be performing their new programme on home ice.

They will go up against European champions Evgenia Tarasova and Vladimir Morozov of Russia.
