I live the south side too, Miller Park in fact, so running along the rivers, parks, docks and tram routes is just ace. I don't think they'd let thousands, (if there will be that many!), run past where I am in the early part of the race but hey, they could always reverse your route no problem. What frustrates the crap outta me is that there's is just soo damn unimaginative and pathetic, sending us out into the countryside for more than half of the course without running through Preston's communities, main roads and great little tracks like yours, but uhm, don't get me started again! Ha ha! Grrrr...
I went to check out some of the new Guild Wheel last week and managed to get a good 5 miles east along the river as far as the Brockholes Nature Reserve. It was brilliant to run on. Note that the tarmac stops there though cos we hit fields and had to scramble through a fence and an industrial estate to get back onto Longridge Road to get home via Ribbleton Ave, so we'll just have to be careful whilst it's under construction.
It's supposed to come to about 21 miles I think when it's finished so it'll be a great training track for lots of us prior to the marathon but I think it'll be much nearer July when the full wheel is ready.
There's tarmac down now out for us out to the docks as well so we've now got a good 7-8 mile stretch along the river out to Brockholes from the very end of the docks. Come summer I can see lots of us doing long runs around the Wheel, but I'm certainly gonna do miles 9-24 of your course for sure, and at some point I'll be doing a few 15-16'ers around their "middle of bleedin nowhere part" .
Haven't checked out any of the northern parts of the Wheel yet but maybe someone else will fill us in when parts of it are ready to run on. By summer we'll be able to handle long runs on it too.
