It was 120 km, about half of which was along the Kennet & Avon Canal. Route 4 actually diverts away from the canal for a good stretch of the journey from Bath to Reading and the more consistent surface of the road was welcome. Then it was back to the rough tow path until I finally abandoned the canal for the A4 for the final few kilometres to Reading. I needed a drink after that and am now suffering the consequences… One cycling day to go. Today: London!
