What's your top speed?

5'7" and just over 80Kg. I've got short thick legs that are pretty powerful (rugby forward, albeit a tiny one). So the power itself does'nt sound like it would be an issue from what you say. Just need to train the cadence and stamina. I wont be running the local marathon this year, so that should help my prep (its 2 weeks before the ride). I'm going to really focus on this.

I realise its not exactly the TDF, its just that all the local Norwegians I know, think I'm just a stupid Englishman with a stupid bike (well to fair the bit about me might be true). I'm dying to put in a decent time, no one insults my bike. WA-bunch of-Cs :)

(ED: Smilie added to avoid insulting the entire country I live in. I'll leave that untill pissed after)

I was gonna offer you a go on my Powertap (that's not a euphemism) but you're in Norway so that's a Distance Fail.

If you want to do this climb fast then you're going to want to be going at your threshold for the duration. It helps if you've done similar duration efforts in order to be able to judge your pacing. Most people start TTs too fast (I know I do).
