Not wanting to interrupt your questions to Brian, but I struggle to understand how your route is any better. The first 9 miles are all along dual carriageways / main roads, which are detached from the communities of Preston. You also have a similar 5mile stretch around Eastway / Tom Benson Way, and although this is closer to Preston, is still detached from most of the population.
The route also crosses / runs along every major route into and out of Preston, so we can either run with the traffic, or prevent anyone entering / leaving Preston on the day.
At least heading out into the countryside may provide something more interesting to look at than the long road ahead. I don’t expect people to be lining the streets where ever the route goes, but at least we might get a bit of encouragement on the way through the villages.
