Gold rush for Ohuruogu in Moscow
Christine Ohuruogu confirmed herself as arguably Britain's greatest ever female athlete by breaking a national record as old as she is to secure a second 400 metres World Championship crown.
When Kathy Cook ran 49.43 seconds in August 1984, few could have predicted it taking 29 years for a Briton to run quicker.
Ohuruogu was just two-and-a-half months old when Cook crossed the line in Los Angeles and has spent her adult life trying to overcome that record.
On Monday night she did just that, producing the run of her life.
Six years after winning her first world crown, the 29-year-old overcame a terrible start to surge down the home straight and pip reigning champion Amantle Montsho to the line by an incredible four thousandths of a second.
Not only that, her winning time of 49.41 seconds saw Ohuruogu break that previously elusive record.
"Today is really special because I got the national record and that's really what I've been working for all season," she said.
"It has been a passion of mine and my coaches to really just strive for the British record because I kind of have everything else.
"I won in '07 and Olympic gold in '08, I have Commonwealth gold, but the national record is as old as I am. It literally is. It was set in '84 and I was born in '84.
"I just thank God that I was able to come away with a win today.
"It was a good field. The girls ran superbly well yesterday and I knew today was going to be hard.
"It was tough, so I'm really, really happy. It feels a bit weird now, like I'm not really here.
"Maybe in a couple of days it will settle down. It's been a whole roller coaster of emotions - it's very intense.
"You're just up and down the whole time. It feels a bit strange but maybe in a couple of days I'll figure out where on earth I am."
The victory was made all the sweeter by her experience two years ago.
Capping what was a third straight injury-plagued season, Ohuruogu was disqualified from the heats for a false start in Daegu - something almost unheard of in the 400m.
She recovered well to take silver at London 2012 and headed to Moscow in the form of her life
It continued there and, after impressive performances en route to the final, she added another world title to the one she secured in 2007, just a matter of weeks after returning from a one-year ban for missing three out-of-competition drug tests.
"I know I'm a lot stronger," Ohuruogu said. "My body's been through war and I knew I'm brave enough to challenge."
