Lord Coe says athletes must recognise their support
Lord Coe has admitted there will be no excuse for underachievement by Great Britain at London 2012.
Despite Government cuts, athletes' funding has been protected through to 2012 and beyond.
Lord Coe told BBC London 94.9: "Elite level competitors are now being supported in a way that no generation before them at that level has been.
"It's very important they recognise that they have a support mechanism that no generation has had before them."
He added: "That's not to say it makes their task any easier. The world becomes more competitive every time we have a Games, the quality of competition, the quality of coaching rises. It does make life even tougher for those athletes."
Lord Coe's comments echo those made by the new chief executive of UK Sport Liz Nicholl and Coe believes the protection of funding can have a big impact.
"In protecting elite level funding, it's not just about protecting the performance of elite competitors," he said, ", and I have always believed that is a very powerful driver."
