South Tyroleans have been successful at winter sports and they regularly form a large part of Italy's contingent at the Winter Olympics. Famed mountain climber Reinhold Messner, the first climber to climb Mount Everest without the use of oxygen tanks, was born and raised in the region. Other successful South Tyroleans include luger Armin Zöggeler, figure skater Carolina Kostner, skier Isolde Kostner, luge and bobsleigh medallist Gerda Weissensteiner and tennis player Andreas Seppi. HC Interspar Bolzano-Bozen Foxes are one of Italy's most successful ice hockey teams, while the most important football club in South Tyrol is F.C. Südtirol, which is currently (2018) playing in Serie C (third highest league in Italy).
