The scheme hit its target of reaching a million children in 20 countries and boosting their lives through sport and play in February this year.
Sport and play is being used to make an difference in their lives as they face issues which can range from gender inequality, gang violence, lack of educational opportunities, to HIV/Aids education and intercultural awareness in countries from Azerbaijan to Zambia.
Lord Coe said: "Inspired by Sport is celebrating the huge achievements of International Inspiration and captures how sport can be a real change for good. I'm very proud that London 2012 is enabling positive change to happen to millions of children and young people around the world. I have been lucky enough to have met some of the young people being reached through the programme and to have seen how it is providing them with more opportunities in life."
London 2012 deputy chairman Sir Keith Mills said: "Having now achieved our original objectives and made such an impact, it's important now for us to focus on continuing and expanding this extraordinary programme as a real legacy from the London 2012 Games."
Unicef, the British Council and UK Sport are all working together on the programme.
Inspired by Sport is free and runs from 2 - 13 May.
