Sarah Mitton crushes own Canadian record in women's shot put with world's best throw this season

With a scorching sun beating down on the shot put circle and a healthy group of fans cheering and yelling in support, Sarah Mitton stepped up for her final throw at the national championships on Saturday afternoon in the Township of Langley, B.C. 

Mitton spun powerfully, letting out a scream as she fired her last throw.

When it finally came thudding to the ground, Mitton knew she had done something special. The crowd did too as they cheered wildly. 

After a length measurement, Mitton set a national record with a throw of 20.33 metres. It's the farthest throw in the world this season.

"Over the moon. It came out of my hand and I knew the second it left it was a big one. It feels so good. I was super excited. And then I saw it was well over 20 and I lost my mind," Mitton said.

Earlier this week ahead of the competition, Mitton told CBC Sports she sensed a 20-metre throw was something she was capable of doing. 

Whether or not that would come to fruition at nationals was a question mark, according to her coach. 

"Quite frankly I didn't expect this here because she's been squatting. She's lifting really heavy. The other day she was complaining about her legs being sore," Richard
