World record holder and Olympic 110m Hurdles champion Dayron Robles is the latest top athlete to confirm he will compete at the Aviva Crystal Palace Grand Prix in eight days time.

The Cuban star, who is unbeaten in five races this season, hopes to continue his terrific form which includes a world best this year of 13.04 seconds.

“I am really happy with how my season is going so far," said Robles.

"I am undefeated in five races and am looking to take this form to London and then of course onto the World Championships in Berlin where I would like to win a gold medal.”

The 22-year-old will come up against strong opposition at Crystal Palace with Olympic silver medallist David Payne and Olympic bronze medallist David Oliver lining up alongside the Cuban, as well as Sutton's Andy Turner, making it one of the most competitive events in a weekend of world class athletics in south London.

Robles however, insists he is up for the challenge.

“My main rival is myself," he said.

"But of course with the other big names due to line up against me I will have extra motivation to put in a good performance for the London crowd.

“I have never raced in London before so I am excited to show the spectators what I can do and it will be the perfect preparation for Berlin.”

The Cuban hurdler is favourite to take the World title next month but Payne will be his main rival as Liu Xhang has not overcome his lingering feet injury problems and David Oliver did not qualify from the US National Championships.

In the women’s event the World Indoor champion Lolo Jones has confirmed she will be compete at the Aviva London Grand Prix.

The 26-year-old American has her eyes on the World Championships in August hoping to make up for her Olympic heartbreak.

2008 had been a great year for Jones right up to the Olympic final but the American was cruelly robbed of a gold medal. When leading the 100m hurdles final, she clipped the penultimate hurdle causing her to stumble and finish in seventh place.
