Start just left of Zoe and work through progressively thinner edges. Your footwork will be tested here. A couple of big reaches take you to a very difficult transition from being splayed out on the wall to underclinging while leaning back to keep your feet smearing on a smooth vertical wall. Work your way along the undercling until it curves up into a layback. The final headwall is easier but the glacier polish isn't forgiving if the earlier sections have left you pumped.
Well bolted, chains at the top.
