While the London 2012 chairman has praised the successful construction process, he admitted that work still needs to be done in time for the opening ceremony a year from today.
"It's a pretty big moment for us,” Coe said. "The Olympic Park venues are in large part built, and though a mountain of work is still needed to prepare them we have an extraordinary platform to build on.
"I feel pride that it's 'sport wot done it'. I cannot look at the Olympic Park without taking great pride that all us in sport did this."
Despite the controversial ticketing system, Coe is adamant that the public are excited about the upcoming games.
"There were 23m ticket applications by two million people,” he added. “That's an extraordinary volume, a world record-breaking demand for any sporting event on the planet.
"There have been 250,000 people applying for the 70,000 volunteer places.
"There is a level of excitement and engagement in every one of our torch relay stop-overs."
Six of the main Olympic Park venues are now ready following the completion of the aquatics centre.
