The Course de la Saint-Nicolas is a Christmas-themed mountain running event held in Krakow, Poland, in early December. It is part of the Grand Prix de Cracovie en Course de Montagne and features several distances: 1.5 km, 3.7 km, 5 km, 11 km, and 23 km.
The race begins in Krakow, Lesser Poland, bringing trail-style mountain running to a major city. Snow is integral to the event's character, and the program includes a vertical race alongside events for children and juniors. The Saint Nicholas theme lends the day a festive atmosphere, distinct from a purely competitive racing environment.
