Jade is press-ganged into running in a junior charity marathon by proud older sis Kayleigh -- who also fancies herself as a trainer. But soon Jade's fed up with the intensive training schedule. So she gets Carmel to switch places. But on the day of the marathon, it looks like Carmel's done a runner -- will her twin, Krystal, have to go through with the race instead?
