Former World Champion hurdler Colin Jackson is taking part in the UK's biggest fun run, which involves more than one million children between May and July 2011.
Now in its seventh year, the event, organised by those behind the iconic Great North Run and Tesco, with support from the Norwich School Sport Partnership, encourages children and their parents to get fit and healthy through exercise and healthy eating.
Three-time world record holder Colin, said: "The Tesco Great School Run is a great way to get children active. It's fantastic to be involved and to see so many children from the area getting so excited ahead of the run."
Other famous supporters include model, TV presenter and marathon runner Nell McAndrew; world champion 5,000m runner Sonia O'Sullivan; Helen Clitheroe, gold medallist in the 2011 European Indoor Championships; Dai Greene, the second fastest British man ever in the 400m hurdles; Jamie Baulch, world champion sprinter and TV presenter and Olympic sprinter Natasha Danvers.
Ruth Girardet, Tesco Corporate Responsibility and Community Director, said: "The Tesco Great School Run is hugely popular with schools and children. It is part of our commitment to encouraging people to get active and lead healthier lifestyles.
"Over four million children have taken part in The Tesco Great School Run since its launch in 2005. This year's event is proving to be better than ever and it's fantastic that more than one million children are taking part."
Chris Jones at England Athletics, said: "As we move ever closer to the London 2012 Olympic and Paralympic Games it is important that we capture the hearts and minds of a generation and inspire children across the UK to get involved in athletics and sport in general.
"We are delighted to have been working with the Tesco Great School Run team to promote the event over the past few years. It is a great experience for the school children who participate and hopefully it keeps them, as well as teachers, parents and volunteers, interested and involved in athletics long after the event."
