GlaxoSmithKline is to energise Lucozade Sport Hydro Active with the first on-pack promotion for the brand.

More than £2m is being spent on a text-to-win competition, which will include TV and outdoor advertising support, ads in lifestyle magazines and point-of-sale material.

The promotion will run from Monday (January 17) to February 16 and will build on the success of last year’s £1.5m Resolution No 1, Start Drinking ad campaign.
