Méga Slalom Ancelle is a long ski slalom held in Ancelle, France, at Taillas in February. The defining characteristic is the course length: 200 gates, making it more of a survival test than a quick club run. Participation is open to those aged 12 and up, and a racing license is not required to enter.
The event begins in the morning and continues throughout the day. Registration is mandatory, with a bib fee of 10 EUR. The course is considered challenging, with the expectation that only highly experienced skiers will complete it. Awards are presented to finishers.
