David Rudisha moves to the front early on in customary style and the Kenyan eases down the home straight to win his heat in one minute 46.89 seconds, with England's Michael Rimmer second and Guy Learmonth of Scotland in fourth.

And if you haven't seen it yet (and you live in the UK), you have 10 hours left to watch the fascinating documentary 100 Seconds to Beat the World: The David Rudisha Story. Well worth it.

Some more video clips that you may have missed that are definitely worth watching.

BADMINTON: Official Jim Gauld is hit in the face by a shuttlecock after a miss-hit shot by Kenya's Joseph Matheri Githitu.

"I'd never seen anything quite like it," says Denise Lewis on BBC One. She is talking about David Rudisha and his world-record run in the London 2012 800m final. The Kenyan star is working his way back from injury and is about to go in the first 800m heat. Watch live here.

After seven of ten events, Canada's Jeremy Warner is the runaway leader in the decathlon. But there's an almighty scrap on for the silver medal.

England's John Lane (pictured) was in second after the first day, but Grenada's Kurt Felix improved his personal best in the discus by four metres to overhaul Lane by a slender margin of 12 points.

Lane's team-mate Ashley Bryant is currently in fourth, but both have strong events coming up, so they could yet improve on their positions.

It's a bit of a procession at the head of the first mountain biking race as only a serious crash or a broken bike looks likely to deny Canadian Catharine Pendrel gold. She leads by one minute, 26 seconds at the half-way stage.

There is a race on for second, though, between Australian Rebecca Henderson and Canadian Emily Batty who are still locked together.

English teenager Alice Barnes is fourth but with a big gap to close to take a medal. Team-mate Annie Last remains fifth with Scotland's Lee Craigie still sixth.

As mentioned, there is a large crowd at Hampden Park. Among those in attendance are the Duke and Duchess of Cambridge, with Lord Sebastian Coe, who won two Olympic 1500m gold medals, next to them.

"That was a great opening race for Eilidh. She was easy, it looked effortless. Sometimes she can be a bit hesitant, sometimes her stride pattern isn't right, but at the Glasgow Diamond League we saw a new Eilidh. She looked good."

After moving into Thursday's final, Eilidh Child tells BBC One: "I've been dying to get out there and get the first round out of the way. It's good that I have a day off to recover.

"The louder the crowd are the better. For the home straight it's great to have that boost to get you home."

A near-full house at Hampden Park witness Eilidh Child cruise through her 400m hurdles heat. She finishes in a time of 55.56 seconds and the silver medallist four years ago will be back in action in the final on Thursday.

As we mentioned earlier, the planned semi-finals has been cancelled, so only one more race for the 27-year-old.

"Eilidh Child is in the best shape of her life. Jamaica's Kaliese Spencer is almost a second faster than Eilidh Child this season, but mistakes happen.

"Last year Spencer came to the World Championships in good form and got disqualified. On paper she's the faster athlete, but can she handle it mentally?"

The mother of judo gold medallist Sarah Adlington tells BBC Radio Shropshire her daughter had to cope with the death of a close friend the day before becoming Commonwealth champion.

Hilary Adlington admits she was "worried" how Sarah would react to the news, but calls her performance "amazing."

Scotland's Sarah Adlington won the women's +78kg gold medal on Saturday.

Weir, who is making his Commonwealth Games debut, opened up a sizeable gap midway through the final lap to finish in three minutes 28.23 seconds, well clear of Australia's Richard Colman and Canada's Josh Cassidy.

The second heat went to Australia's Kurt Fearnley (3:19.64) with English teenager Will Smith also through to the final after finishing third but there is drama on the final lap when Ghana's Patrick Obeng clips the kerb and takes a tumble when in contention for a final place.

It was a question that had to be asked. On Monday we had Nick Matthew v James Willstrop, who aren't the best of friends, in the men's squash final - today it was another English pair, Greg Rutherford and Chris Tomlinson in the long jump qualifying.

Earlier this year, Rutherford set a new British record of 8.51m to shatter the previous mark held jointly with Tomlinson by 16cm. Tomlinson said the new record should not have stood because it was a foul jump. So do they still speak to each other?

"We do talk and congratulate one other," said Tomlinson. "Rivalries are good. We want to beat each other. There's no harshness there. There are a few guys I have fractured relationships with though."

The mountain biking is in full flow and Canada's world champion Catharine Pendrel is flying across the Cathkin BraesTrail, leading Australian Rebecca Henderson and compatriot Emily Batty by a minute with four laps to go.

England's Alice Barnes and Annie Last are fifth and sixth, ahead of Scotland's Lee Craigie.

Jersey last won a Commonwealth Games medal 24 years ago, but they have high hopes of a top-three finish from Barry le Cheminant and Dan Richardson in the final day of the Queen's Prize individual competition.

Le Cheminant, 50, last competed in the Games at Edinburgh in 1986, but retired from the sport to be with his family.

"I took time off as my children were growing up," he said. "Spending half a day or a day at the range, does impose on your family time. I wanted to be there when the children grew up."
