Some years ago when I was doing my research on runners' speed variation with gradient, I had some correspondence with the organiser of the Silsden Murder Mile. They were quoting some grossly inflated figure for the amount of climbing, and I persuaded them to change to what was apparent from the OS map, which is just over 150 metres.
But I haven't had any success with the Tryfan Downhill Dash. The organisers still insist that the finish is 69 metres below the surface of Llyn Ogwen.
