Now we have the latest and greatest GPX I see that Pen-Y pass isn't used, and there is no A470 back and the Harlech route is used for both directions!
Haven't done that since 2006!
Pity there's a control at Llananthony or we could use the Golden Valley route from Hay
Anyway, looks great. Probably will be touch and go if I can do it in the time limit
