142m, 7 pitches. A brilliant, sustained trip crossing the central section of the main cliff.
7 pitches - 5b,5a,5c,5b,5c,5c,4c. The third pitch descends the Alien chimney from the Rat Race belay. There is a trick to this involving the spike at the start of the main pitch of Positron.

A fantastic excursion which we felt deserves E4 for the Alien chimney descent (pitch 3) and the majority of Citadels 2nd pitch (pitch 6). Led pitch 1,3,5 & 7. A wonderful day out.
