Pujada a la Mola per Nadal is a Christmas morning trail outing in Matadepera, near Ca’n Robert, within Sant Llorenç Natural Park. It is a short uphill event, approximately 3.8 km with about 450 m of climbing. The outing is intended for those who wish to reach La Mola on foot rather than compete for a time. Club Muntanyenc de Terrassa organizes it, and the format is intentionally non-competitive, allowing participants to run or walk.
The event began as a group of friends ascending the mountain and has been organized since 1983. Over 300 people, frequently exceeding 350, travel from across Catalonia for the Christmas climb. It was competitive until 1995, but its current focus is simpler: to share the Sant Llorenç mountain on a holiday morning, appreciate the natural park, and make the ascent together instead of pursuing personal bests.
