What does one do about spectating on these things? never done it before... Do I pick a spot by the road and settle down for the afternoon?
Get to where you want to see it (uphill bits are the best because they don't whizz by so quickly). If you're driving, find somewhere nice and clear of the road to park and wait. This doesn't have to be in dedicated parking, up on a verge is fine, but try to keep the road as clear as possible, obviously. Road closures don't normally come into effect until around 10-20 minutes before the race comes through, but if you're at a busy section then you'll want to be there sooner to find a decent spot to park the car. We usually get there two to three hours in advance, but depending on how busy it is, where you can park or anything else to factor in you could leave it later. For example, if it's coming through the centre of town you oughtn't need to worry about transport, so it's up to you when you want to find a good spot, although remember that the crowds can be pretty big.
Then it's basically wait around. Approximately ten minutes before the race comes through, Anthony McCrossan will come along in a Tour car to tell everyone who's in the break, what the time gap is etc. Except for at the start/finish areas, the roads are immediately open upon the passing of the race.
As for more detailed routes, if you can't find anything online yet (strange how the south west stage details are already out but not some of the others) then usually in the month or so before the event you can expect a detailed pdf map to appear on the Tour of Britain website.
