While the men's FKT for the BGR goes all the way back to 1982 and Billy Bland's 13h53m, an outstanding women's FKT was recently (23 April 2016) set by Jasmin Paris at 15h23m. Paris' time beat the previous FKT of 18h6m set by fell running legend Nicky Spinks the previous year, and appears to be the 5th fastest time ever. An early report of the accomplishment is here, and in interview with Paris is on Ian Corless' Talk Ultra podcast (Episode 110, interview starts about 3:14 into the podcast). Paris published a detailed report on her run, complete with splits, on her blog.
