Cold temperatures can often be a climber's friend, increasing friction and turning once impossible holds into viable options. Too cold however and the risk of numb extremities can limit a climber's chances of success as they struggle to maintain both concentration and grip. During his push attempt on 'Sendero Luminoso,' Nik Berry was tested to his absolute limit as cold winds sapped his strength and precision on the crux pitch. However, with a little luck and a serious amount of effort, Nick managed to maintain his composure; putting the climb together in a single continuous push. This marked the first time that the route, an old Steve Quinlan aid line, had been successfully free climbed. Nik's success came, in no small part, thanks to his fellow team members David Allfrey, who climbed with him on the push and Mason Earle, who climbed all of the route's pitches clean during separate sessions.
