This is the page of itineraries for the SWM MX5OC International meeting in May 2018, each of the four downloads are zip files containing all the routes of the specified type.

The links to MyRoute-App below are links to the actual route definitions in the tool I used to create the itinerary files. If you click the route link, it asks you to either log on to your existing account on MyRoute-App or gives you the option to register for a FREE account where you can then see and use the route source. For more information on MYRoute-App, follow the link.
If you choose to do Drive 2 to Devil’s Bridge, take care through the Elan Valley, look out for sheep on the roads crossing in front of you as you approach. See the youtube video here.
