The preparations for this year's Make Your Mark Challenge, part of the London 2012 Inspire programme, have been more exciting than ever before. As an avid Hollyoaks fan you can imagine my amazement when I heard that Max and OB from Hollyoaks (they don't have real names!) were coming to the Make Your Mark office to film a teaser video clip.

Make Your Mark Challenge is the UK's biggest free enterprise competition for young people. Over 45,000 young people from schools and colleges across the UK will be competing, pitching enterprise ideas to be crowned this year's 'top banana'.

Max was tasked with guarding the super-secret Challenge brief until 17 November 2008 when it will be unveiled to launch the beginning of the Make Your Mark Challenge. OB wasn't really sure what Max was on about at first but soon got the idea. Both of them have had to 'protect the brief' against an aerial onslaught of giant inflatable bananas.

If you didn't know already, Enterprise Week is going global this year as part of Global Entrepreneurship Week. Due to its massive success in the UK (in large part through competitions like the Make Your Mark Challenge), we're now in 75 different countries! In Singapore there'll be an entrepreneurship 'treasure-hunt'; in the US there's an online competition for creative industries; in Australia there's a speednetworking event at the Sydney Opera House and in Nairobi there's a music concert themed around enterprise.
