LONDON (AP) — The head of the London Olympics says, apart from a wrong turn, the final buildup for the London Olympics is going fine.

With 10 days to go until the opening ceremony on July 27, that's the verdict from Sebastian Coe.

The arrival of athletes got off to a bumpy start Monday, with American hurdler Kerron Clement tweeting that the bus taking him from Heathrow Airport to the athletes village got lost for four hours.

Coe told a news conference Tuesday that "apart from a misturning and a couple of tweets we're in pretty good shape."

He said Clement's bus journey actually took 2 1/2 hours and that most athletes reached their destination without any problems.

Coe says "98 percent of these journeys went without a hitch at all."
