More than 100 primary school pupils from Portadown will get the chance to try everything from volleyball to martial arts at a special sports day on Tuesday.
And they will be helped by volunteers from Craigavon Senior High School and Oasis Youth Club.
With 500 days to go to Rio 2016, the organisers of United Games area hoping to inspire and motivate local students.
The initiative, which is a partnership between Unity Sport and Craigavon Intercultural Programme (CIP), will be held at Craigavon Senior High School with the support of local sports clubs.
It will involve P6 children from Bocombra, Presentation and Seagoe Primary schools, while Craigavon Senior High pupils and Oasis Youth Club members will help out, aided by corporate volunteers.
Eight teams will be competing against each other in a variety of activities including volleyball (Craigavon Aztecs), tennis (Portadown Tennis Club), martial arts (Evolve) and Olympic performance and life skills.
The Games are designed to help young people create new friendships and encourage children to explore new sport activities.
Another aim is to give young people the opportunity to volunteer alongside senior corporate volunteers, thus upskilling young people and introducing them to possible career opportunities.
Richie Smith, Unify Sport, said, “We have been involved in a number of London 2012 community based activities and designed United Games as a legacy project that promote the next generation of young leaders to help local schools get involved in a range of different sports that they may have never tried before.
“The volunteers work to inspire, support and encourage the local school pupils as they try out different sporting activities on the Road to Rio 2016 and that could become a lifelong passion.”
Initiatives such as United Games are delivered through CURBS to encourage cross-community friendships and provide young people with new opportunities which will improve their quality of life and sense of well-being.
The 2016 Olympic Games will open on August 5 - followed by the closing ceremony on August 21.
