Thousands of Olympic fans sail through London's transport system in time for the day's events at the Olympic Park.
But the biggest surprise of the day so far has not been during competition, it's the smooth operation of London's notoriously busy transport system.
"I expected to have a bit of trouble, so I've left home a lot earlier than normal but I'm here 45 minutes door to door all the way
from Chelmsford so really really good actually, surprised. Like I say I expected an hour and a half journey in this morning but absolutely no problems at all," said Dominic who works in Stratford.
Fellow commuter John agreed.
"Yeah, I'm only here from Mile End so it's a bit crowded, didn't get a seat but it's fine, not too bad," he said.
Many of the fans were in the park for the hockey.
"So it's my first Olympics and it's a fairly important event 'cause I'm a big hockey player, so I really wanted these tickets and I got lucky but unfortunately I can't see Belgium as they're playing tonight but I'm seeing New Zealand and Australia, so I'll support these teams," said Alex from Belgium.
China currently leads the medal table ahead of the United States while hosts Britain are yet to win their first gold.
