Alastair Chalmers says he was inspired to reclaim his British 400m hurdles title by his new-born son.

Chalmers beat Joshua Faulds by 0.31 seconds to win back the title he lost to Tyri Donovan a year ago, his sixth national crown in seven years.

His fiancée Ellie Bell gave birth to Robert on Tuesday morning, external – four days before the opening round of races.

Bell brought baby Robert to the Alexander Stadium for the final, with Chalmers giving his new son an emotional cuddle after his victory.

“I’ve pretty much not trained all week and my head’s not really been in the game because I’ve just been thinking about other things of course,” he told BBC Radio Guernsey.

“It’s been lovely just thinking about my boy, but when I made the decision to go do the champs, I knew it was going to be a hard one.

“Definitely the heat on Saturday was very tricky, I felt like absolute rubbish the whole way round because my body just hasn’t been firing from no training, and of course just being tired.

“But I got it together for Sunday, and when he came up, I just couldn’t lose – I had to win for him, didn’t I?”
