Vittel has chosen London's 20 Golden Square sites ­ floodlit sites in dense traffic flow areas ­ to promote its £1.8m 2001 Fluid Thinking campaign for Vittel Natural Mineral Water. The posters will be up from April 16-30 to coincide with Vittel's sponsorship role in the Flora London Marathon on April 22 and will feature the 75cl sports bottle in a Marathon Man execution. Vittel supplies 750,000 bottles of water on race day. The brand will make a further appearance on the sites in the summer with posters featuring a woman on a bike. Vittel is also running an on-pack promotion to raise £10,000 for the official Marathon charity, the Multiple Sclerosis Society. {{MARKETING - P&P }}
