As well as sorting out decent clothing I'd advise sorting yourself a heated visor or modify your existing one with either stick on reactive foil strips or reactive wire. I tried using a neoprene face mask to prevent my visor from freezing on the inside but it failed dismally left me with a choice between constantly stopping to clear the visor or riding with it slightly open and suffering.

Another tip is to fit a few screw in studs to the soles of your boots because it's very difficult to pick a bike up when you keep falling over and you really do want to get it upright and out of the way as fast as possible. Crashing close to a corner when you know any vehicle coming round that corner is going to struggle to stop is a real trouser filler and not for the faint hearted.

If you use a Scottoiler to lube your chain then be warned that the standard oil will freeze but we tested a low temperature version for them and it worked very well. I'm not sure if it's on the market yet but if you contact them then I'm sure they'll be able to help out.

You'll have a great time and I'm looking forward to seeing how far you get. Don't forget to get prior permission to go through the locked barriers so you can do the final part of the trip or you'll have to try and ride around them and could end up in trouble.
