Edu Marín can finally stop climbing upside down: After six months of effort, he has freed Valhalla, his behemoth 304-meter roof project in the Great Arch, Getu, China.

Marín reported on Instagram, “TODAY, WE HAVE CLIMBED VALHALLA!”

Previously, Marín had redpointed all of the pitches individually. The route consists of 14 pitches rated, in order: 7b+ (5.12a), 7a (5.11d), 8a+ (5.13c), 7c+ (5.13a), 9a+, 8b+ (5.14a), 8a (5.13b), 8c+ (5.14c), 8a+ (5.13c), 8b (5.13d), 8a+(5.13c), 8c+ (5.14c), 8a+ (5.13c), 8a+ (5.13c). The first four pitches ascend the vertical wall to reach the roof, and the rest of the pitches climb the horizontal roof, to a shorter, still severely overhanging headwall at the cave’s entrance. While the roof spans some 304 horizontal meters, in total the route covers over 450 meters of terrain when the opening pitches are factored in.

In mid-February, Marín finished the final, hardest piece of the puzzle by redpointing the 5.15a crux-pitch which he dubbed “Odyn’s Crack.”

After that, the only thing left to do was send every pitch consecutively in a ground-up push.

Supported by his father, Novato, and brother, Alex, Marín started up from the back of the Great Arch on the evening of March 19. At 4:00 am on March 20, just nine hours after he began climbing, he completed the first full redpoint of Valhalla.

He described the moment of finishing on Instagram as a “special feeling: sunshine, wind, no expectations nor pressure, just training. … Exhausted right now, but happy: frustrations, cryings, joy, fails, travels, pressure, difficulties… But WE did it today!”
