Cardiff - Newport - Trelewis

Reverse of the listed route map. Tarmac surface route taking in the Cardiff levels, the Sirhowy valley, and the Taff trail. We'll cut out the part down to the bay, and use the new cycleway to get out towards Newport road, and modify the route slightly depending on what bikes people show up on to avoid a short gravel section of required.
Stopping at 14 locks cafe if wanted.
