Women's heptathlon
Katarina Johnson-Thompson needs a solid throw in her second shot. Here she comes - 11.68m.
That is not very far at all. Her lead could be under threat here.

Very comfortable for Laura Muir as she jogs her heat to finish third and easily qualify. The heat was won by Dawit Seyaum in 4:05.33.
Muir straight through.

Women's heptathlon
Jessica Ennis-Hill for her second of three shot puts. Bang - only 13.34m though. That's 10cm down on her opener.
As it stands Nafissatou Thiam will extend her lead in silver spot and could even go into the lead.

Brendan Foster
Olympic medallist and BBC athletics commentator on BBC OneLaura Weightman struggled in the back straight there. When Hassan came flying past her I thought that was a chance for Laura – she should have gone with her but there wasn’t any response.
But she’s the fastest loser. She’ll have a bit of a nervous sweat on but she’ll be quite confident that six athletes won’t go faster than her.

Women's 1500m heats
Laura Weightman has just been speaking to BBC One, after she finished seventh to leave her relying on being a fastest loser to reach the semi-finals.
"I should go through in that time, it was a bit silly not to go through automatically," she said.
"It was a messy race, but that’s championship racing and hopefully it’ll get me through.
"Hopefully I’ll get into that semi and be fine. There were a few silly mistakes in that race but I know I’m in good form."

'Disappointing crowds'published at 00:49 British Summer Time 13 August 2016
Tom Fordyce
Chief sports writer in RioDisappointing crowds again in Estadio Olimpico. May be slightly fuller than morning session, but it's a marginal one. It's only day one of track and field, but so far Rio isn't so much embracing the athletics as offering a half-hearted wave in the distance.

Women's 1500m heats
Laura Weightman finishes seventh in her heat, she'll have to watch the clock as only the top six went through.
The heat was won easily by Sifan Hassan with Faith Kipyegon just in behind.
Six fastest losers from the three heats go through. That could be enough for Weightman.

The first heat was won by the great Genzebe Dibaba in 4:10.61. So not the fastest time, which may help Laura Weightman qualify.
Under way.
