Yes OK. I just wondered why the 80s.
I recognise "received wisdom" but assertions about "the greatest" are usually tendentious because of the criteria adopted - ie the writer can decide what conclusion they wish to reach and work backwards to justify it.
Context is all.
And I think "records" can be seductively misleading - Andy Styan's Langdale record dates from 1977.
And if the 80s were so great what have Messrs Hope(s), Bailey, Jebb, Booth, Holmes,... been doing all these years?
But as to your real question: probably. I think there are currently several outstandingly good female runners over certain distances and terrain but the current euphoria should not erase the memory of some other great female runners in the past like the wonderful Anne Johnson and peerless Angela Mudge - and Sarah Rowell may have never bothered with a BGR but she was still a half-decent runner in her day.
Maybe when you reach The Fellrunners of the 90s you will form another opinion? Part 2 of my index is ready for the printer!
