Most difficult climbing route in the USA: Seb Bouin climbs Suprême Jumbo Love (9b +)

French professional rock climber Seb Bouin climbs an old Chris Sharma project at Clark Mountain. The route called Suprême Jumbo Love is the most difficult route in North America with a difficulty of 9b+.

Seb Bouin is unstoppable. Just over a week ago, he managed the Endurance Hammer Jumbo Love (9b) to be repeated at Clark Mountain (Lacrux reported). Now he doubles it with the even more difficult direct variant, which adds another 20 meters of hard climbing in the ninth French degree to the line. He baptizes his first ascent Supreme Jumbo Love. With a proposed rating of 9b+, he makes the line the most difficult route in the United States.

«It couldn't have gone more perfectly than ending this climbing trip with the direct start of Jumbo Love.»

Suprême Jumbo Love: 70 meter endurance hammer

20 additional meters of really hard climbing up to the actual crux of Jumbo Love, make the direct variant a sustained effort. "And then follows the second part of Jumbo Love, which is physically very demanding and pumping," says Seb Bouin. The highlight of the route was the last few meters of slab climbing.

Suprême Jumbo Love is around 70 meters long. According to first ascent Bouin, the main difficulty is to combine everything. So the tricky 9a at the beginning, the crux of Jumbo Love, the exhausting exit from the overhang and the final record.
