Rowing
Alan Campbell - the first Northern Irishman to represent in four Olympic Games - and the bronze medallist in London 2012 is about to get going in his semi-final.
Still absolutely piddling it down at Lagoa.
Mahe Drysdale of New Zealand is the favourite for the title, nevermind this race.

GB's Katarina Johnson-Thompson finishes second in her heat of the 100m hurdles in a time of 13:48secs.
That's 1053 points in heptahlon money...
It's a soggy track and a pretty empty stadium at the mo... No more rain falling though.
Jessica Ennis-Hill is up in the last heat...
Here she goes...
rowing Campbell's busy route to glorypublished at 13:57 British Summer Time 12 August 2016
Alistair Magowan
BBC Sport in RioYou have to feel for the single scullers like Britain's Alan Campbell. Not only do they have to pull themselves across 2000m all by themselves, but they have to contend with the greatest number of rounds too.
Take the eights for example, win your heat and you're through to the final. But London 2012 bronze medallist Campbell has already contended with a heat, and a quarter-final before today's semi as he aims for another chance of glory in tomorrow's final.

I hope he at least had a beer or something to celebrate.

The sport is huge in South East Asia and the Thailand fans are out in force to support their teams.
They've also got the Brazilians on-side too & cheers of "Thailand, Thailand, Thailand" are inter-mixed with the occasional "Brazil, Brazil, Brazil!"
If they're this excited about the group stage they may need restraining come the knock out phase!
GB's Chris and Gabby Adcock are due on shortly for their second game of the tournament and looking for their first win.

shooting Did you know?published at 13:48 British Summer Time 12 August 2016

Image source, .Shooters practice being in as relaxed a state as possible. Research has shown the intuitive right side of the brain takes over before a shot, rather than the analytical left side.
For this reason some shooters advocate distraction training. This is where they think of something else and let their muscle memory take over for the shot, thus preventing over thinking it.
It’s been shown that it’s best to hold your breath on shooting and to shoot between heartbeats. The biggest thing facing a shooter it seems is themselves.

End of twitter postDay five or day jive? There must have been something in the Rio air yesterday as we saw waltzing weightlifters and dancing at the tennis.
