Tring Hill from Aston Clinton

Tring Hill is very often the last climb on rides that I do, whether on my own or in a group. As such, my legs are normally pretty tired by the time I get there. For this reason, the group often plans to go up The Holloway via Drayton Beauchamp instead, or avoid much climbing altogether by going round by the reservoirs.
However, I'm here to talk about Tring Hill. It's actually a pretty good climb, on the scale of dead straight climbs at an almost constant gradient. It follows the line of the Akeman Street Roman road, but I doubt that the Romans dug the cutting that helps to even out the gradient, or built the embankment that evens out the gradient lower down. This large scale civil engineering must have been done later, when this road was improved as a national trunk road (the new A41 now bypasses it completely). There are two lanes going up the hill, so traffic is never a problem from an overtaking point of view. The climbing proper starts as you go past the Indian restaurant Mela, and then it's a case of digging in and trying to hold a constant speed until the top. This will be when you find out that the gradient is not completely constant, and it gets a little bit steeper after the B4009 turning!
