The route will stay as it as done in recent years, Chester services to Bala, Bala to Betws-y-coed via Ffestiniog then Betws-y-coed to Denbigh by 2 parts of the evo triangle then back to Chester. To be honest there are a lot of first timers again who have never done it and the route is very good. Everyone will be either be able to download or sent the full route details shortly. So no real need for a test run
Looks like Shire wrote some of that
