‘It’s crazy’ as Sarah Calvert shocks Laura Muir in ‘biggest upset of weekend’

Her victory in Birmingham came a week after she took silver at the Summer World University Games in Germany.
“I thought last weekend at the world juniors was a big breakthrough, but this is crazy,” she told Scottish Athletics.
“It’s crazy. I didn’t expect that to ever happen, never mind this year.”
With the UK Championships doubling as the British trials for the World Championships in Tokyo next month, it turned into a slow, tactical race.
Calvert’s winning time of 4:16.27 was eight seconds slower than her own personal best, with England’s Walcott-Nolan finishing third and Giffnock’s Wallace edged into fourth.
“I know a slow, tactical race definitely plays into my hands,” she added.
“These girls have much faster PBs than me, so if they went out to try to run 3.55, I wouldn’t be able to stick with it, so when it goes slower, it levels out the playing field.”
