As promised, here is a relatively (maybe) brief run-down of the kit that I used in the Spine Challenger. Now, you might be wondering why you should take advice from somebody who DNF'd, but whilst I never managed the final few miles of the race, my kit choice allowed me to get through the distance that I did cover in comfort and with almost no ill after-effects. Of course, I say kit choice, but really I took what I could get, borrowing large amounts of gear from my brother-in-law Trevor. Luckily he is awesome, and that kit proved to be excellent! Right, here we go:
In My Pack
Backpack: Osprey Talon 33
This 33 L backpack is a relatively lightweight pack for a race like this. I wasn't sure at first that I would fit everything in there, but it is incredibly roomy with lots of additional pockets for secreting all of your gear. I put my roll mat, stove, sleeping bag, dry bag filled with spare clothes and dry bag filled with miscellaneous gear in the main compartment, my micro spikes in one side pouch, head torch in the other, mobile phone in one front waist pocket (for photo opportunities), lots of gels in the other front waist pocket, maps in the rear pouch and food in the top pouch. This kept everything nice and easy to find when I needed it.
I used the 3L bladder that came with it (although only used 2L at most), which has a very neat magnetic system for holding the feed tube across your body and out of the way. I used an insulating cover on the tube (stolen from my old-style Salomon running vest), and was sure to blow water back into the bladder to help prevent water in the tube freezing. The final weigh in came in at about 7.5 Kg without water, so I was probably carrying a maximum of 10 Kg. As the race went on, I ended up wearing more of the clothes from my pack, so it got a little lighter as well. All in all this was a pretty good weight, and I did very well to end up with such a light pack without having to spend the earth for some of the über lightweight gear.
I was a little worried that I would suffer from chaffing issues, particularly as the race was in fact the first time that I had ever run with it (it was borrowed from my brother-in-law). But actually it was very comfy, and didn't ride up or rub at all. If I ever do anything similar to this race again, I'll probably buy myself this pack.
