Miriam Kennedy: Hannah Cockroft is absolutely amazing
Baroness Tanni Grey-Thompson
11-time Paralympic champion
That was a superb race - Kare had such an amazing start but Hannah did not panic and kept going.
Hannah was looking down at her front race wheel and was concentrating on her own race. That was a really, really amazing race for Cockroft.
Second for Kare Adenegan. Superb. Carly Tait came fifth.
In a world record 17.18 seconds....
Lots of faces of excited fans covered in union jack flags. Supporters applauding, racers on the line.
It is almost time for Hannah Cockroft.....

This is Michael and his dad. They're on the hunt for British athletes. Michael says the javelin has been his highlight so far - until Hannah Cockroft is up a little later.
Yep, Cockroft is out on the track, gearing up for the race.
Yep, Hannah Cockroft, Kare Adenegan and Carly Tait race in the 100mm T34 final at 20:55 BST.
Jo Butterfield now sits third and Kylie Grimes fourth in the club F51 final.
Ukraine's Zoia Ovsll leads with a championship record 23.73m.
Butterfield will need to throw a personal best if she wants to win.
A little more on Colombia's Dixon de Jesus Hooker Velasquez now. Apparently he wanted to pull out of the event but was not allowed to under competition rules after he had been declared to compete by his country.
So he ran 400m - quickly - and stopped and is technically given a did not finish rather than a disqualification.
The first of those 800m heats has been won by Canada's Liam Stanley.
In the F32 club final Gemma Prescott has had her six throws and currently sits third. She must now wait and see whether her best of 19.97m is enough to secure a medal.
Just a couple of T38 800m heats between us and Hannah Cockroft running in the final of the 100m T34 final - that takes place at 20:55 BST.

And here is Ed Warner, talking all things World Para-athletics on Radio 5 live.
Colombia's Dixon de Jesus Hooker Velasquez is absolutely flying in the 800m T38 but stops after 400m, just stops. Walks off, as though he thought it was a 400m race. Most of his track record indicates he is a 400m runner. Truly bizarre.
The heat was - unsurprisingly - won by Ireland's heavily fancied Michael McKillop. The 27-year-old is pursuing a fifth consecutive 800m world title.
Kyle Grimes is currently third after her first three throws in the club F51 final - she has a best so far of 18.43m.
Jo Butterfield is second.
The men's javelin F46 final is underway.
Former chairman of UK Athletics and co-chair of London 2017 organising committee Ed Warner on 5 live: "I'm delighted to have both the World Para-athletics and the World Athletics Championships at the same venue in August. We are delivering the same quality to both championships and that is a big statement.
"It is astonishing they have not taken part in the same city before.
"We have 280,000 tickets sold and looking at the crowd here, we have 19,000 for this evening, which dwarfs the crowd for the first session in Rio last year.
"We have 30,000 tomorrow and Sunday and loads of kids here on Monday. The atmosphere should be fantastic."
Kylie Grimes in action now in the club F51 final.
Jo Butterfield is currently second, behind American Cassie Mitchell.
There are three finals taking place at the moment - the club F51 final, the F32 club final involving Gemma Prescott and Abbie Hunnissett and the men's shot put F57 final.
The fourth heat of the T12 100m has been won by South Africa's Ndodomzi Ntutu in a time of 11.05 secs.
Zac Shaw, remember, won the first heat a little earlier.
