Correct in grammar perhaps, but the idiom is "Last one to the ...", and your alternative sounds very stilted and should be "gets", nobody would actually use it. There are lots of ways you can challenge a person to a race.

If I beat you to the campsite you'll have to do the cooking. Okay?

Note, racing in cars on the public road is illegal.
