Road trip, food & lack of exercise

[crazycanuck]

I'm a bit concerned about our upcoming road trip. We will be driving for about 3 1/2 4days, 12-16hrs on each one. This applies to the return road trip as well.

I know we can bring fruit, raisins, drink mainly water but i there are a few small issues..

We can't take fruit into South Australia
There aren't any health food type shops between Perth & Broken Hill(NSW) and beyond..
It's hard to find good coffeeee along the way

Exercise-this might be a bit hard & the only chance we'll really have is when we change drivers. That and it might be 43C in some places & no shade.

Any ideas?

We're renting bikes once we get to Auckland & will be doing some mtn biking . I even get to meet MillieNZ
