Here's an article discussing lifting and cycling (although I think aimed more at road cyclists):

I'd suggest cardio 3x and lifting twice. Mix up your cardio, try intervals, some all out sprints with partial recovery, long distance boring stuff, etc.
As far as diet, eat
adequate protein (try 1g/lb bodyweight), EFAs (6 fish oil capsules a day at least, some flax oil), and fiber (vegetables, fruit). Make sure you get adequate carbs for that which you are depleting, unless you have been following a
high fat diet, in which case continue that, just eat less.
BTW, I'm from Parkersburg, are you doing 24 Hours of Canaan this year?
