Richard and Peter Chambers go for gold at London games
All eyes will be on Great Britain's rowers later as a team of four, including two Northern Ireland brothers, go for Olympic gold.
Richard and Peter Chambers, from Coleraine, are firm favourites for rowing gold in the lightweight men's four final which is at 12:10 BST.
The NI pair, and team mates Rob Williams and Chris Bartley, won their semi-final in 5:59.68.
"We are in a good place," said 22-year-old Peter.
His brother, Richard, 27, said they were trying to keep focused on the job ahead.
"We'll just have to go out and do our thing and see if we can win that gold medal," he said.

"The mind does drift every now and again: What would it be like to win that gold medal, standing in front of a home crowd? But you've just gotta put it out of your mind.
"We've got a job to do, we can't be overwhelmed by it. There's now six boats that could win the Olympic gold, we're one of them.
"We've got to beat five other boats to it, and five world class boats, so it's going to be a tough job but one we think we can do."
Sir Steve Redgrave, who won his first gold medal in 1984, has predicted gold for the Chambers brothers.
Only three other competitors from Northern Ireland have won gold medals in the summer games; Mary Peters, Jimmy Kirkwood and Stephen Martin.
The Chambers brothers discovered their rowing skills on the River Bann as teenagers.
The brothers are one of the big hopes.
They've looked very good in the semi-finals, very good in their heat.
But it's lightweight rowing and it all comes down to the day.
It's probably going to be the tightest finish of this regatta.
The boys are very cool, they are very calm, they'll just do their job.
The rowers are staying quite close to the course. The investment has been put in.
This has really become a sport that Great Britain leads the world in.
Peter, a world champion, took up rowing at Bann Rowing Club in Coleraine at just 13 under the guidance of Seamus Reynolds.
Richard, is a two-time world champion, who competed in the Beijing Olympics four years ago. He began rowing at the age of 15, under the guidance of coach Bobby Platt, MBE
Both men studied at Oxford Brookes university.
Jeff Bones from Bann Rowing Club described the brothers as "two cool, calm customers".
"Those guys know that they are capable of doing it, but they know that the other boats round them will be strong and want it every bit as much as they want it," he said.
"They know what they have to do. If it's a close race, which it will be, the crowd will lift them, they'll want to do it for the crowd, for the whole of the UK. "
He said the event would "go down in history".
"Two guys from the one family, from the one club, representing Great Britain in the Olympic final of the lightweight fours, it's unbelievable," he said.
Pastor Trevor Watson from Coleraine Baptist Church said there was great excitement in the town. A big screen has been erected inside the church for supporters.
"We're hoping to have old and young from right across Coleraine," he said.
"Whether win or lose, we are supporting them and we'll think as much of them," he said.
A sell-out crowd of 35,000 people is expected to cheer on the team at Eton Dorney.
You can tune into the race on BBC One, Radio Ulster and it is being streamed live online at 12: 10 BST.
