"Singletrackworld is a forum for mountain bikers. Many of whom are male."
Moast of them seem very clued up, but some seem to deliberately make stuff up to muddy the water (I wonder who does that regularly?).
There is one guy saying that Brigid Kosgei's new women's marathon record of 2h14m04s, is the 15th quickest of all time for men or women, which is an absolute pile of twaddle. The men's record has been broken 23 times since 1964, when Basil Heatley did 2h13m55s, so I reckon thousands of men have gone faster than the current, yet to be verified, women's marathon record.
