This year, Nike marks 25 years of the Just Do It campaign with ad challenging public to take on its stars, Serena Williams, Gerard Pique and LeBron James. In its new advert, Nike has called in sporting legends including King James – the NBA’s Most Valuable Player – world number one tennis player Serena Williams, Gerard Pique of FC Barcelona and Spain, and boxing sensation Andre Ward. And the ladies will be delighted to know that Bradley Cooper narrates the sequence, which also features a guest appearance by actor Chris Pine. From August and into September Nike will be challenging you to #justdoit – “Run The Distance” will task you and your friends to run a marathon in a week and sporting challenges against Nike stars will also be thrown into the mix, which will be tracked on a live leader board. Check out the video and let us know what you think in the comments.
