Olympic 400m champion Christine Ohuruogu will go head-to-head with reigning world champion Sanya Richards-Ross at the Aviva London Grand Prix at Crystal Palace on August 13 and 14.

It will be the second time in a little more than a month that the pair will clash, with them also scheduled to face each other at the Aviva British Grand Prix in Gateshead on July 10.

Ohuruogu said: “I last competed at Crystal Palace in 2008 and was really pleased with my performance.

“This year I am competing against the World Champion and I am hoping for another win and an even better performance.

“Sanya and I will be pushing each other all the way which will hopefully mean a quick time.

“We have enjoyed some great battles over the past few years; in Beijing and Berlin and I’m looking forward to yet another one, this time in London.”
