Whitelow Lane isn't a long climb, it's more of a hidden gem or a short-cut route to the quieter roads from the south side of Sheffield. Abbeydale Road can be rather busy, especially during rush hours and weekends. The right turn up to Totley Townhead will get your legs warmed up and is a more severe gradient than riding up to Owler Bar, but it's sure fire way to get you onto the quiet roads within only twenty minutes of setting off from the town centre.
Once you reach Townhead then take take the left turn past the butchers and go right through the village. Then there is a small descent before your onto the bottom of Whitelow Lane. From there on in you can take your time on the climb up to Hathersage road and soak in the view as you climb out of the valley.
It's only a one mile long road with a gradient of 7.1% but you will have already done the climb up to Townhead which is touch in it's own right and by the time you've reached the little-kick-up onto Hathersage road, my guess is you'll be grateful when the roads flattens out.
