I wasn't going to leave anything out there - Chalmers

Alastair Chalmers says he was "not going to leave anything out there" as he dramatically qualified for the semi-finals of the 400m hurdles at the Olympic Games.

The 24-year-old from Guernsey threw himself over the line to finish third in his heat and gain direct entry to Wednesday's semi-final.

Chalmers is at his first Olympics after making the qualifying time at the British Championships when he had a disqualification overturned.

"I came down the home straight and I could see it was all pretty close," Chalmers told BBC Sport.

"I'm not going to leave anything out there am I? Who cares if it's the heats? These heats are like previous Olympic semi-finals.

"I'm through to the semi-final, a nice day off tomorrow and then back on Wednesday, so I'm looking forward to it."

Chalmers emulates his brother Cameron who ran in the 4x400m mixed relay at the last Olympics in Tokyo.

And he said he was inspired by the support he got from British fans and supporters from the Channel Islands.

"To have my home people come out is a dream in itself, I love the people from Guernsey," he added.

"I'm repping them underneath the GB flag, but the team's amazing, we're so strong this year."
