A Caribbean activity holiday is up for grabs as part of Unilever's £3m marketing push for its AdeZ juice drink.

The 'Discover Your Strengths' campaign kicks off next month backed by an on-pack promotion. It will give consumers the chance to win one of eight places on 'Strength Island', where they will do activities to build mental/physical strength.

Winners will be joined by sports presenter Kirsty Gallacher and cricketer Mark Ramprakash.
