'It's crazy' - Calvert shocks Muir at UK Championships

Sarah Calvert "didn't expect that to ever happen" as she beat Olympic silver medallist Laura Muir to the 1500m title in the biggest upset of the UK Athletics Championships.

The 24-year-old Livingston AC runner's personal best is 15 seconds worse than her fellow Scot.

But, just as Muir looked to be bursting through on the inside to overtake Revee Walcott-Nolan and Erin Wallace in the final straight, Calvert powered past all three on the outside to win the biggest race of her career.

Having been told that her victory was described as "unbelievable, the story of the weekend, a fairytale" during BBC Sport's live commentary, Calvert said: "I think they're pretty acurate."

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."
