The British Olympic Association was one of just nine National Olympic Committees (NOCs) to celebrate the inaugural Olympic Day in 1948 but it has now grown into a global celebration with millions coming together to share the Olympic spirit. In 2012 almost four million people in more than 150 nations took part in events promoting sport under the motto 'Move, Learn, Discover'.

On 23rd June 1987 the Olympic Day Run was launched by the International Olympic Committee's (IOC) Sport for All Commission to encourage NOCs to celebrate Olympic Day, and for more than a decade the University of Bath have organised the largest celebrations in the UK to mark the day.

At the nearby Sheldon School in Chippenham, their Olympic Run - the largest in the country - was the curtain-raiser to their annual Sheldon Olympic Week. Beginning with an Opening Ceremony and a 3km run, they even had their own Sheldon Olympic-inspired flame that burned throughout the week's festivities.

All over the country schools joined in on the fun. Mackie Hill J&I School in Yorkshire had already held a 'Global Week' for pupils to learn about the cultures and sports of other Olympic nations before their own sports day in which children were rewarded for living the Olympic Values of Friendship, Excellence and Respect.

North of the border schools across Glasgow celebrated Olympic Day, showing the city's passion for the Games.

St Pius X Primary School in Dundee also celebrated by creating a gallery of Olympic and Paralympic inspired paintings before their sports day.

In Belfast, Dundonald Primary School not only hosted their own sports day, but sent a group of pupils to an inclusive sports day organised by Disability Sport NI.

Llanfechell Primary School in Anglesey promoted healthy living with their sports day by rewarding those children who brought the healthiest food in their lunch box.

And in the South East, Ulcombe CE Primary School combined their sports day with a Summer Fair.

This year the University of Bath helps the local community celebrate International Olympic Day with a Family Fun Day that included a mobile climbing wall, zip wire and free taster sessions in a variety of sports - even bobsleigh.

The university also hosted a 5km run with a 3km version for under 16s and children were kept entertained by 'Sportacus', from television's Lazytown, throughout the day.

Regardless of age, gender or athletic ability, Olympic Day encourages people to get active and reflect on the meaning of the Olympic Games - that we must always try to give the best of ourselves, while the important thing is not winning or losing but knowing how to play the game well.

All of these schools have received some special prizes to thank them for sharing their stories. If your school has a story to share, just upload a case study here and you could be in with the chance of winning some prizes too!
