(It would take several hours to reach the ambush, yes, but after battles the victorious army would often harry the retreating army. Particularly if Whiterun was at war with Falkreath (which they are), their forces were strong (which they are), and they were only fighting a small army (which they are, as far as they're aware) they would press the offensive.

As for the army not being able to supply themselves forever. They can't, but they can definitely last a few weeks. They're quite close to a settlement, and they have hunting to help feed themselves.

Obviously this does hinge on the idea that Whiterun would want to press the offensive, but if they did (which is perfectly plausible) the plan is valid.)
