Government, any Government, wants sound bites - a quick win which shows the public just how well their new policy has worked. The headline which vindicates their work.
And so far, where legacy is concerned, there are plenty of these good news stories. The UK economy has seen a £9.9 billion ($15.1 billion/€11.5 billion) boost in trade and investment, one in three foreigners are now more likely to visit the UK on holiday and according to the Active People Survey 1.4 million more people are taking part in sport every week than before we won the bid.
Indeed our own Sports Club Survey - the largest ever survey of British sports clubs – shows that adult membership of clubs up and down the country has risen by 20.6 per cent since 2011. So too with youngsters, an 8.4 per cent rise in members in the last year alone.
This is all really positive stuff. And with some of these demonstrable benefits clearly a direct result of the Games it'd be easy for Government, to think "job done".
But legacy isn't about sound bites. It's not about political gains. It's about us - the British people.
This is our once in a lifetime opportunity to make a fundamental change to the way we live our lives.
This legacy must be about embedding physical activity into the lives of more people than ever before - forging a new healthier, happier world for our children and our children's children.
And with this in mind it's not "job done" for Government or for us. It's "good start, what next?"
We need an effective, coherent long-term school sport policy, which accommodates a broad curriculum including both competitive and non-competitive sport. The Government's two-year primary sport premium is a good start but securing sustainable funding is crucial if we are to capture the excitement the Games created amongst youngsters and turn it into something tangible.
We need to make sport and physical activity a part of everyday lives. Cycling has become inextricably linked with the morning commute for millions of Britons through a greater awareness at a town planning level, increased exposure, political advocacy and the sheer enthusiasm people have shown for it. This must be carefully nurtured and encouraged, along with walking and running, so that we begin to see the kind of cultures that have thrived in countries like Denmark and Holland fostered in the UK.
We need to make sport and physical activity more accessible for all. The Paralympics worked wonders in challenging perceptions but only 18.2 per cent of disabled adults in England play sport once a week. Mainstream sports clubs need to be better equipped and clubs guided so that we can accommodate the burgeoning interest.
We need more volunteers. The Games Makers - such an unexpected success story of the Games - gave people a sense of what volunteering in sport could be. But we need so many more at club level. This is a legacy that everyone can contribute to, and it's time that we rolled up our sleeves and joined the near two million people who volunteer week in week out in England alone.
And crucially, we need recognition from policy-makers that sport and physical activity provision is not a drain on resources but instead a sound long-term investment. If local authorities are forced to cut their sport provision, by as much as 40 per cent in some areas if reports are to be believed, this country may save money in the short term. But future generations - perhaps even your generation - will be hit hard by this short-sightedness and health and social costs will spiral to a point which we can't reach.
We are in the midst of an obesity epidemic, our population is ageing and in the time it takes Usain Bolt to run 100 metres the NHS spends £10,000 ($15,000/€11,500)in treating preventable illness. This will only get worse. No, sport, recreation and physical activity aren't panaceas. But the research base behind their value in preventative treatment is compelling.
We've made a great start on the legacy from the Games and roots are beginning to take hold. But it's not job done, it's what next?
