Just checked weather again, seems that rain is less likely (20%), wind forecast is a light breeze and a bit warmer, up to 15 degrees. If that turns out to be the case then that's pretty damn good in my book. Might not need that waterproof after all.
I've decided to take my camebak too, going to half fill the bladder and then stuff the waterproof in with it as there's not much room for anything else apart from phone and a car key. Will also take running belt for gels and jelly beans. Can't access the camelbak pockets on the run so the belt is good for stuff you need whilst running and the camelbak for stuff you don't need (or hope you don't need)
I find the camelbak is great for sipping on whilst running and then can use check points for proper refreshments.
So you reckon a backpack is the way to go then - I have given that some thought as I run my longer runs with a 1.5L camelbak but it has close to no storage space so only any good for water, couple of gels, phone + keys and that's about it. I have a suitable trail backpack with bladder but was erring on the travelling light and just going with my running belt which has 2 pockets + 500ml water bottle. What with the changeable weather however maybe the backpack makes more sense and then I can drop the belt and carry a few extra bits that might come in handy.
Thanks for the feedback on the shoes as well, they look good but my Garmin Forerunner packed up completely on Sunday, won't even switch on or soft/hard reset so have had to drop some unexpected cash on a replacement, having said that it's done about 6 years so can't complain too much - timing sucked though but new one arrived today thankfully. That's the problem with relying on gadgets for pacing etc, leaves you feeling exposed without them.
This is my first marathon too so have the same mix of anxiety and excitement as many others posting. I feel I am as prepared as I am going to be but what about the weather? The forecast looks like showers, a bit chilly (11 degrees) especially before noon and a bit windy. I assume the route is exposed so any tips on clothing would be appreciated. I would normally have no problem with a short sleeve running top and shorts but with some of the hills at 1mile+ and walking there is going to be time to get quite chilly without any extra layers, especially if wet.
I was therefore thinking of tying my water/wind proof running jacket around my waist just in case? Any views or experience to call upon would be most welcome.
As far as shoes go I will be in road shoes as they are the only pair I've got although I understand water runs off the course pretty quickly so hopefully this should be okay if a bit careful on the slippery bits. If it had been wetter in the run up I might have broken in a pair of trail shoes but hopefully will be okay without.
