Where to stop on the way to Bike Park Wales?

We're off to BPW in a couple of weeks, from Hull (or thereabouts). It's a few days trip, so I'm looking for options to ride on the way. 

The Long Mynd is currently top of the list - it's mebbe an extra hour of driving, but I quite fancy a day there (I rode there once mebbe six years ago and remember it being decent if chilled, which is about right for what we need). 

Is there anywhere else on the way? Mebbe Malverns? We ride the Peak quite often so probably not there. 

Open to suggestions!

(Current itinerary is Long Mynd Friday, BPW Saturday, Brecon Gap Sunday, either FoD or just come home on Monday)
