Not a bad kit.
I do some trail running when I am not in lazy mode. I usually run with less; a knife, whistle, Photon, mini bic, water bottle and a Patagonia Houdini jacket which is super light.
I would not worry about water containers (condom, oven bag) as you are carrying water already. Just use the empty container and some MP1 tabs.
I run with a BM mini grip of some sort; one handed, locks is super light and easy to grip with sweaty hands. I wear mine clipped inside the waistband of my shorts just behind the right hip; it doesn't move and I can grab it just like when it is in my back jeans pocket.
I might suggest adding a AMK Heatsheet or blanket bivy since you are minimally dressed.
How about a little first aid?
Do you need the Spider wire? What for?
