A fun and easy chimney climb as long as you don't fall and pinball your way down to the ground. Stand start and work your way up the left face towards the top of the "Shillings" arete with good hand and foot holds. Two-thirds of the way up you will transition over to the "Lobster" boulder for the top out.
The route is in the gap between the Lobster tail and Shillings, across from Hobbit Hole. The start is on the left once you enter several feet into the gap from the Hobbit Hole side, there are several visibly good handholds. Get down the back side of the "Lobster Tail" boulder or boulder hop down to the beginning of the Marathon.
Helmet, no room for pad or spotter.
