The campaign, created by Sid Lee, launches today (July 2) and features TV and outdoor ads.
It is being supported by a large-scale digital output across a dedicated site, www.adidas.com/all2012, Facebook and Twitter, using the handle @adidasUK, with a dedicated hashtag #takethestage, which will run for the next six weeks.
Adidas, the official sportswear partner for Team GB and an official Olympic sponsor, uses Olympic UK athletes Jessica Ennis, Tom Daley, Louis Smith and Phillips Idowu in the TV creative, each narrating their own ad.
Athletes Pete Reed, Laura Trott and Olympic footballers feature in the digital activity.
The creative uses footage of the sports stars and monologues by the athletes, describing their personal journeys and their pride at taking the world stage in London this year.
Nick Craggs, marketing director, Adidas UK, said: "It is time for the Adidas brand to 'Take the Stage' and the plan we have in place for Games time will ensure that, not only are we highly visible as a brand, we also connect with all audiences with a unique campaign that showcases our sponsorship of both Team GB and the London 2012 Olympic and Paralympic Games.
"Working closely with Team GB athletes we gain a unique insight into the highs and lows of their personal development and we wanted to try to capture and share these emotional journeys."
