GlaxoSmithKline is flexing nearly £10m of marketing muscle behind developments to its Lucozade Sport range. These include a new grapefruit flavour, a 500ml pack in four flavours, a 29g lemon sachet, and a mixed berry pouch in singles and 3 x 330ml packs. A Have you got it in you?' ad campaign featuring a motivational coach character will hit TV screens in April, backed by national press ads and posters aimed to coincide with the London Marathon. Other activity includes sponsorship of the British Lions tour to Australia and an on-pack promotion to win a trip to a match Down Under. {{MARKETING - P&P }}
