“When the gun goes, you’re free and I think you saw that quite clearly with Phoebe’s running, but the other thing that is important in Phoebe’s progression is her racing brain.

“To be able to be the best 800m runner, you have to be able to think on your feet because even if you go into a race with a plan, you can’t control what the other competitors are doing.

“She went into that race and didn’t want to to front run but unfortunately no-one took it on, so Phoebe had to then change her plans, (but) hold herself back – which she does find quite hard – and then wind it up over the last 400 and she demonstrated that supremely. That’s what makes her such a fantastic athlete.”
