Saturday marks the latest milestone in the countdown to the Games, and Coe said: “We are exactly where we would want to be, if not a little bit ahead.
“With only 1,000 days to go now, we are very excited. We have a lot of hard work to do, but we are closing in.
“If you look at the money raised to stage the Games in a difficult economic climate, we are in great shape.”
Organisers have regularly denied the global recession will hinder Britain’s ability to deliver on the promises it made when it won the right to host the event four years ago.
They insist all commitments will be met – and International Olympic Committee president, Jacques Rogge, has recently declared himself happy with Britain’s progress.
Questions remain over a suitable venue for badminton and rhythmic gymnastics, but Lord Coe remains optimistic about delivering a world-class Games and leaving a legacy which inspires the next generation of sportspeople.
“I want to see a legacy in every form of sports participation,” he added. “I want to see more young people involved in sport.
“I want to see more young people doing things they wouldn’t normally have thought about doing – and, of course, I want London to leave world-class venues not just for athletes but for our young future competitors as well.
