“The tactics weren’t planned at all,” said Cockroft. “Going out I said good luck to Kare and that’s about as much as we talked.
“She’s got a really strong start so she went forward and as soon as the speed dropped off I shouted up to her and said: ‘If you want to pull out I’m here’.
“So she pulled out and I picked up the pace which created a gap between me and Alexa.
“It was really nice that for the first time me and Kare could come out and work as a team and show that if we work together we could put a good performance in.
“This is racing – this is what it is.”
Halko was in agreement: “I think it was very strategic and I loved it because we haven’t had kind of strategy in a while and it surprised me.
“But it was great. I think it’s positive – that’s what the 800m is about. Just do what you have to do.”
Having also claimed T34 100m gold on the opening night of competition, Cockroft will attempt to take her career world title tally to an incredible 10 in the 400m on Thursday.
“I’m feeling pretty confident because that’s my favourite event,” she said.
