At the last moment, I decided to ride out to Balerno along the Water of Leith on the muni. I’d ridden out to Roseburn (and back) before, but this was substantially futher. It was lots of fun (except a few wrong turns) and, because I had a bit of time pressure (I was getting a lift back from Balerno) I realised that I could actually go substantially faster than normal without too much difficulty.
Endomondo says 17km in 2h, which means about 5.3mph. Allowing for the wrong turns at miles 9 and 11, and a few pauses, I probably ride at about 6mph. That sounds about right – I’ve previously thought that it was about twice walking speed, or something around jogging pace. I’ve overtaken a handful of joggers, and followed a few others for a while.
