Today's Bike Ride

I now know it was West Lane. And thanks to Veloviewer (1.7km) I now know why I was wondering when it would level out!

Length 1.7 km
Average gradient: 9.5%
Maximum gradient: 20.1%
Elevation gain: 160 m
Elevation change: 159 m
Min elevation: 127 m
Max elevation: 286 m

Looks like you missed out there: I've just had a look at the OS map, and the Ellers road has 225m of climbing, including a double chevron on the lower section.

Wharfedale Harriers organise an evening one mile uphill road race - "Murder Mile" - out of Silsden which climbs around 500 feet in the mile. The road only serves a farm or two so is hardly used (otherwise it could not be used for a race with 200 runners including children).

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.
