On 17 September 2019 British rock climber Emma Twyford successfully redpointed Big Bang at Lower Pen Trwyn in North Wales. This hugely underrated 9a was first ascended by Neil Carson in 1996 and, at the time, was first 9a to be established in Great Britain. The route has been repeated previously just once, by James McHaffie in 2011, and in redpointing this stamina fest Twyford became the first British woman to climb 9a. Her efforts are documented in this film.
