Hope so because 50 minutes with most of that travelling through Bath was too much in a tight space with Tony!!SatnNavs don't seem to like Bath. It's one of those places where you get a completely different route on the way back. But it's always going to be fiddly because there aren't really any practical routes to the M4 that completely avoid the built up areas and 20mph zones. Meadowcroft to M4 on a Sunday should be about 20-25 minutes.
Rich will set you right.
