2 weeks to improve fitness!

Hello 
In a fit of insanity a few weeks ago I have entered my first ever MTBing enduro in a few weeks (on the 23rd Jan) :shock: I'm in the 2 hour event, and the course is about 7 miles I think....
I'm pretty fit and I usually ride a couple of times a week, but compared to my buddies (and i'm sure the majority of the people there) who do miles and miles on their road bikes, I am going to be sooooo slow
. So, the question is, is there anything I can do in a few weeks to improve my riding fitness without completely exhausting myself?
I rode on Monday, went down the gym Tuesday and rode again last night and my legs were like jelly (not helped by the flat tyre I noticed when I got back to the car :? ) - I don't want that happening on the day or it will be very embaressing!
Any advice gratefully received

Life is not measured by the number of breaths you take, but by the number of moments that take your breath away....

Also, don't do a big effort 3/4 days before the events, so you are well rested
Which race are you doing?
Any training like that is about quality not quantity!
It might be worth trying to pace yourself as you don't want to burn out too soon.
