This ride takes in the iconic climb known as The Tumble. At 3 miles long with an average gradient of 8% it's a tough 'un but it is do-able as thousands of weekend warriors discover every year when they ride the closed road Velothon Wales. And when you eventually reach the top, most of the next 17 miles is spent descending. You can cut 14 miles off the route by parking in New Passage Road near the southern end of the old Severn Bridge. Note that the ride starts at 9 am. https://ridewithgps.com/routes/28406077
The route mentioned above has been amended ever-so-slightly. After reaching Pontypool we head in the direction of the Llandegfedd reservoir visitor centre's cafe on the way to Usk. If you downloaded the original, delete it and download the new version (use the same link).
Our first scheduled stop is Annettes Cafe in Abergavenny. We'll stop here for a bit of lunch and a rest before we tackle the Tumble which is just a couple of miles from Abegavenny. I won't be refilling my drink bottle competely at the cafe, to save weight. I'll probably pop in the fuel station in Blaenavon and buy a drink that will do until we get to the visitor centre cafe.
