If you play by the rules I play by, which I'm pretty sure are the legitimate rules, you've just lost the challenge assuming that you have no other Pokemon. :T
But you're early in the game, so you can really do as you like. I know some people play with the "Soft resets", which I'm personally against, as a way to avoid losing Pokemon in rival/gym leader battles.
