Riding along the Rigole is one of the most beautiful rides I've ever had. It's at least 50km of gentle downhill on a single trail, wooded and therefore shady. I didn't meet any other cyclists and only met five walkers. The corners of my mouth were constantly almost at my ears, absolutely fantastic!

Tasty crepes to reward anyone that’s made it up the hill from the south.
