getting championship fit in 3 weeks

i know its a bit crazy but been given 3 weeks notice for a weeks national champs that i'm crewing in. want to do well and am usually pretty fit,

just want some advice on getting as fit as possible in the time

cheers

3 weeks off and go sailing alot

Get yourself a roadbike and ride that every day (start off
doing like, 10 miles a day and gradually build it up)

TT's bang on the money.

I do exactly that every year, and it works a treat

1)How old are you?
2)How fit have you been in the past?
3)How long ago was that?

If you're still sub 30 yrs old
You were very fit
And it was less than three months ago.

Then three weeks would do it, with minimum 3 times a week hard at it. By
hard at it I mean full on exercise of the type you're likely to do and
preferably twice the duration.

Either way, don't just do nothing, three weeks hard at it will at the very
least sharpen you up and a sharp body = sharp mind which will not do
any harm at all.

Don't listen to the pie eaters, if you want to do well, being fit is
paramount, as I've realised these past few weeks not being that way, in
fact I'm just about to join you over the next three weeks funnily enough.

One thing my new boat needs is someone fitter than me in my current
state to pilot it..
