For 150 years, canals were the high-tech water machines driving the industrial revolution. Amazing feats of engineering, they carried the rural into the city and the urban into the countryside, and changed the lives of everyone. Then, just when their purpose was extinguished by modern transport, they were saved from extinction and repurposed as a 'slow highways' network, a peaceful and countrywide haven from our too-busy age. Today, there are more boats on the canals than in their Victorian heyday. Writer and slow adventurer Jasper Winn spent a year exploring Britain's waterways along 1,000 miles of 'wet roads and water streets' where he discovered a world of wildlife corridors, underground adventures, the hardware of heritage and history, new boating communities, endurance kayak races and remote towpaths.
