Finlay Wild, one of Britain's best fell runners, set the FKT at 3h14m58s on June 16, 2013, as reported by www.ukclimbing.com, which also lists some splits for the trip. Wild went back just a few months later and lowered the FKT another 15 minutes, just breaking the 3-hour barrier at 2h59m22s. ukclimbing.com has the story and interview.
"In theory I could go faster - but the motivation of breaking a whole number is definitely strong, so now that I have done it, I am happy with the record - for now." - Finlay Wild
