My son bought me Simon Warren’s Cycling Climbs of Yorkshire - meaning ‘ard cycling climbs, since when he has logged his accomplishments on Strava and, naturally, as his father I have to do the same.

Today was Hartwith Bank out of Summerbridge - maximum 18.9%, badly broken-up road surface, so dark under the trees you need lights to be seen by descending vehicles - near Pateley Bridge. Pateley Bridge delights by being situated in the deep River Nidd valley so every road out goes up and steeply.

So 44 miles, 3600 feet and a max pulse at 300% of resting.

Such a challenge having a cycling son. I think I’ll just have daughters next time round.
