Local sports clubs will be encouraged to host volunteer open days and events on the anniversary of London 2012, in an effort to continue the volunteering legacy of last year's Olympics and Paralympics.

Join In - set up last year to maximise volunteering opportunities following the Games - launched the campaign last week, urging local clubs to sign up for the summer event.

Join In 2013 will run from 27 July to 9 September marking the one-year anniversaries of the Olympic opening ceremony and the Paralympics closing ceremony, with a matchmaker service linking volunteers to clubs.

A Join In survey revealed seven out of 10 local clubs need more volunteers, and despite 82 per cent of Olympic volunteers stating they are interested in sport, only 15 per cent currently volunteer with local sports clubs.

During the Olympics and Paralympics Join In worked with local sport clubs to stage over 6,000 events across the UK, which saw 300,000 attendees and created over 30,000 volunteers.

Prime Minister David Cameron said Games' volunteers were one of the highlights of London 2012.

"We all want to harness that spirit and ensure that what happened last summer is the beginning of a great volunteering legacy for our country," he said.
