The Merino Muster is New Zealand's only XC ski marathon, and has been running since 1995. The event is held at Snow Farm, NZ's only cross-country ski field based 1500m above the Cardrona Valley.
Snow Farm’s trails and surroundings have attracted international cross country and biathlon ski teams for many years.
The cross country ski trails roam across the lower part of the Pisa range. Many follow old farm and mustering trails while others were formed to exploit the topography and shaped for snow retention.
