South Downs Way, Southern England
This is the only national trail in England that can be mountain biked the entire distance and it’s quite challenging, particularly when the full 160km is ridden in a weekend as many outdoor enthusiasts do.
The riding is generally non-technical but difficult, with a number of ups and downs, many of which are steep. The views are stunning, particularly towards the coast. And the airiness of the ridges, and large skies, really provide a sense of place. There’s some nice pubs and cafes along the route, too.
