Start in between Impact Day and Sixpence at the obvious groove in the centre of the wall. Climb the groove (straightforward but poorly protected) then trend left to a junction with Impact Day at the overlap (rest and good runner on the left). Climb the middle wall of Impact Day, past a stacked knife-blade peg, to the horizontal break at two-thirds height. Make one move right, arrange your last protection and then blast directly up the headwall to gain a faint groove for the last six feet. The climbing on the headwall is technical and sustained with the last few moves providing the crux.
