Neveresting Hafjell is an uphill endurance race on a ski slope at Hafjell. Participants start at the bottom, ascend to the summit, descend via gondola, and repeat. The objective is to accumulate vertical meters. Some aim for a single ascent, while the most demanding option targets 27 ascents, simulating climbing Everest at Hafjell.
The event allows participants to set their own pace, with options for continuous effort or breaks. It attracts individuals of various ages and backgrounds. The 6-hour category is accessible to participants aged 8 and up, families, and those seeking a shorter uphill challenge. In this category, completing eight ascents is "climbing the Matterhorn," providing a distinct intermediate objective within the overall Everest-style challenge.
