When Emma Twyford powered, crimped and screamed her way to the top of The Big Bang at Lower Pen Trwyn, she ended a three-year battle and entered British climbing’s history books as the first British woman to break the 9a barrier. This 30-minute film by filmmaker David Petts of Volo Digital is her story. It follows Emma Twyford’s three-year battle to climb The Big Bang at Lower Pen Trwyn in North Wales. Graded 9a, The Big Bang is one of the UK’s hardest climbs and had only previously been climbed twice in its 23-year history. David Petts follows Emma’s journey to success, capturing epic footage on The Big Issue (E9) in Pembroke, Mind Control (8c) in Oliana, Spain and big walling in the Dolomites. This Volo Digital film for BMC TV won Best Climbing Film at Kendal Mountain Festival in November 2019.
