One of my long planned targets but not achieved yet is the Cymru SR. For this year I've entered a 600 (Benjamin Allen's Summer Outing) and a 400 (Hafren), but I'm struggling to make any dates for a calendar 300. Plan B is to travel across to Wales for a weekend and ride a couple of the Cambrian Series permanents, doing a 300 on the Saturday and a 200 on the Sunday.
Using the Audax UK event page links, I can see the route for each perm, and I know they can be ridden from any control point. Is there a map anywhere with all the routes shown, or could somebody suggest a good combination of rides (300 + 200, preferably not overlapping too much) which could share the same starting location? I'm looking to base myself somewhere within easy access from the M6, maybe Newtown or north of there.
Many thanks if somebody can help.
