the roads from preston to lytham aren't actually that good. preston is a bit of a sprawl and then it's just straight a-roads all the way to lytham. plus there's speed cameras everywhere. a more enjoyable route (and just as quick) is to carry on up the M6 and onto the M55 but come off at kirkham and go the back roads to lytham. i don't mind leading the convoy, i know it quite well up there
