On 21 July 2022 Seb Bouin completed the first ascent of Nordic Marathon, an extraordinary 130m outing at Flatanger in Norway graded 9b/+. The route crosses the most overhanging section of the cave and connects the first pitch of Nordic Plumber (8c) with the second pitch of Thor's Hammer (9a+), before tackling the headwall and exiting at the top of the huge grotto. The climbing is so demanding that the Frenchman could only make one proper attempt every two days.
