Toni and I did a walk near Stroud and Cirencester today. It was 11 miles, which was longer than usual for us – perhaps in training for our upcoming trip to Nepal! It's been a dry sunny day, which was great for walking, and part of our route was along the derelict Thames and Severn Canal which I'd never heard of before. It opened in 1789 and closed in 1911 as costs of maintenance outweighed income. We started our walk in Sapperton, where the canal enters a 3109 metre tunnel – one of the longest in the country.
