Perseverance.

The Water of Leith Walkway is a public footpath and cycleway that runs alongside the small river of the same name through Edinburgh, from Balerno to Leith.

The concept of a public path first appeared in 1949, but the necessary construction work was not begun until after 1973. Nowadays, it provides access to many interesting sights, like the Scottish National Gallery of Modern Art and the Dean Gallery.

The path starts next to Balerno High School and runs 12.25 miles to Leith. Apparently, the path runs downhill, but the incline is so slight that it is barely perceptible. Try telling that to my legs when I'm cycling in the other direction!
