@jdanielp I also walked across the aqueduct and was slipping quite a bit. It was quite slippy overall but not too bad. I had the towpath to myself most of the way so I used the middle bit a lot and avoided any sharp turns. As a precaution I also dismounted at the Wester Hailes S-bend but it was fine.
It was definitely more sparkly around Ratho and I could hear loads of crunchy noises under my wheels.
But I was sending my first message just before my morning meeting so I didn't have time to elaborate! :)
