For those who want to bone up on the intricacies of sailing, you can do a lot worse than reading this article. www.ctvolympics.ca

Derek Burnett has missed 5 targets in his first round today. Looks like he won't progress now. Hard luck.

@PeterTowe @RebelDevil71 Mr Towe, in your comment of 10:31, instead of "take note" you really ought to have said "take a hike".

@Will Downing a discussion on RTÉ there Will about Mark English - David Matthews said he's the best young middle distance runner Ireland has had since Eamonn Coghlan. He and Jerry Kiernan said he should have been sent having gotten the B standard, as experience for Rio. What do you think?

@RebelDevil71 Totally agree. If you have a B standard in an event, you're eligible - it's only OCI/AAI regulations that deem B standards unacceptable. They'd have nothing to lose, and he could turn out to be another Derval O'Rourke - a pure Championship athlete who puts in great performances when needed on the biggest stage of all. I think we're seeing too much good talent being kept at home through this policy of A-standard only. Other countries throw in a few Bs for good measure, and I believe they benefit from it.

Derval O'Rourke's semi-final draw tomorrow night.... potential?

@Will Downing Hmmm. Is it the top two go through automatically Will, and then 2 fastest losers?

Sebastian Coe will look into why 100 metres world champion Usain Bolt was prevented from taking a skipping rope through security.

The wind is said to be fairly blustery and all over the place. Even trickier.

Ger Owens and Scott Flanigan are off the pace in the men's 470 race, down in 25th about 1 minute 40 seconds behind the leaders.

Here's an interview I did with Annalise Murphy. She's a fun girl www.daraghoconchuir.ie

Top two then two fastest losers in the 100 hurdles, as there are three semis. She's up against it, potential of some big names going out from those eight.

The names and countries to watch out for in Annalise's race are Lijia Xu from China, Marit Bouwmeester from the Netherlands (Both of who are joint top on 34 points) and Evi van Acker from Belgium who is level with Annalise on 33 points.
