Sharing the opening four moves with Mécanique Elèmentaire (8B+), Jour de Chasse was claimed by Jan Hojer in December 2013 and takes the most obvious line directly up the center of the boulder.
Like Mécanique Elèmentaire, the problem starts on a crimp rail with a dynamic reach to a large sloppy pocket. The climber then requires traversing out to another large pocket before reaching a sloper on the lip of the boulder, the crux of the problem requiring strong body tension to complete the sequence. It then tops out with a final four moves of sloping open hand features before topping out.
When Jan made the first ascent of the problem in 2013, he used a more dynamic beta for the first move, requiring him to stop his swing on the first sloping pocket with one arm. Since then, repeaters have found a significantly easier starting beta, opting to use a high left heel hook which removes the need for the powerful dynamic move to the pocket.
Since Hojer’s first ascent, the problem has received over a dozen repeats, becoming a Fontainebleau test piece for the bouldering elite, with repeats from big-name boulders like Jimmy Webb, Nalle Hukkataival, and Giuliano Cameroni.
Personal suggestions generally put the grade in the 8B-8C area, with some climbers making light work of the problem, including Webb, who claimed an ascent after 15 minutes.
