[Why does he need to start at 7 am assuming one or two drops and tipped at Tooting by 12.30 either way ?.
Why does he need to get to Wrexham that same evening I’m not saying that’s going to happen.I’m saying close enough to finish the run early next morning ?.
How long do you think it takes to get from Erith to Wrexham. 
So we’ve got around 15-6 hours total from loading up to arrival time take daily rest and break out of that.
I’m guessing that the guvnor isn’t planning on not taking a reduced daily rest period here.
I’m also guessing it can be more than 9 hours though.
I’m also guessing the 7 am arrival time isn’t set in stone.
I’m guessing something along the lines of Erith to Hilton Park services.
Then Hilton Park to Wrexham.
Break is obviously going to be wherever most convenient and according to the clock.
No one said tachos are easy to work with.
It could have been a 9 o’clock start or a 10 o’clock start with however many drops, it didn’t really matter, but now you’ve just made it so much easier with your insistence that he has a really late start.
So in that case he only had the 6/7 pallets to get rid of that day. We’ll start him at Cobham again at 11 o’clock this time with 1/2hr to ¾ hr to get to Tooting and the same 1.5hrs to Erith, so that’s 2 ¼ driving used and there’s been no need to take any breaks because of the late start.
Leave Erith at 3.30 pm so he must have 45 minutes by 5.45. He’s at Thurrock just before 4 having been on duty now for almost 5 hrs so it seems reasonable enough have a break now, it makes things simple because he’s got to have a WTD break by 5pm anyway which makes South Mimms just a little too far to make by 5 o’clock with any certainty.
4.45 leave Thurrock, we’ll forget about all the traffic around the area at that time of day and have him straight on the M25 at 4.45. According to AA route planner he’ll make the 160 miles to J3 M54 or the M54 services in 2hrs 40 minutes… er at 60 mph average speed (for a car.) That’ll be 7.25 and its 43 miles to go and 1 hr to Wrexham…… in a car.
Now let’s do that motorway section again when we aren’t in Cloud F**** cuckoo land. He’s not going to average 56 either so I’ll give you 53/54 and that’s generous. That means 3hrs give or take a minute or two. 7. 45pm and it’s still 43 miles and one hour to Wrexham . 8.45pm
You can put him in Hilton Park overnight if you like, he’ll do that in 2 ½ hrs at 60 mph average from Thurrock so 7.15. Restart in the morning at 06.15. Leave after vehicle checks at 0630 arrive Wrexham 07.45.
You can play around with the day as much as you like : get him away at 3 o’clock, but unless he takes his break while loading which we’ve already established isn’t happening because he can’t do it legally, it will always be as I said a ‘just’ manged to do it, with the potential for a lot of stress and concern about trying to maintain speed in heavy traffic. Without the 9 hrs overnight, which we had eliminated because no planner should assume it to be possible, it was always going to be difficult. The goal was 7 o’clock, we go with what we are given not make excuses. I’d try to do it, in a sensible manner, but I’d point out that success would be unlikely unless the booking time was put back. There is absolutely no way I’d be joining in the silly buggers nose to tail race. I’d be knocking back the speed limiter to around 53 in the busy sections to let them all pass me and have myself a relaxing drive.
Who knows we may have someone on here who does Wrexham to Dartford Tunnel regularly and can rubbish this.
Although maybe not within + or - 2 minutes of the essential non negotiable, make or break, deal breaker 7 am deadline.
