The Bristol-Bath Railway Path has markings at measured 100m intervals
along the length of the Avon Valley Railway (it also has a measured mile
between the Bitton and Riverside stations), which I used to calibrate my
computer.

That's interesting. I've ridden it a couple of times but just didn't notice
- it's also about 100 miles from here :-(

It's worth bearing in mind that tyre pressure makes a small but
noticeable difference. My old commute used to be measured at 5.37 miles
at 100psi, 5.38 miles at 90psi and 5.39 miles at 80psi. I use my trip
distance for the ride to work to tell me when I need to to my tyres up.

There's a pot hole[1] at a nominal mile from home and that gives me some
idea, although temperature also makes a difference.
