Rudisha, coached by Mallow’s Brother Colm O’Connell, used his customary front-running tactics but ran at a slower more controlled pace than usual. Passing 400m in 54.17 seconds it seemed the Kenyan kingpin was leaving himself wide open to a host of fast finishers, but there was no stopping him in the home straight.
“I was very confident coming here,” said Rudisha who has struggled with a serious knee injury since winning the Olympics in 2012.
“I’ve been working on my speed I think this is really special despite the fact I was coming from a bad injury that almost pushed me out of my career. My coach (Brother Colm) was like ‘go there focus and win and everything else will be forgotten’.”
