Phillips Idowu will take on his leading rival for Olympic triple jump gold this summer, Christian Taylor, at the Aviva London Grand Prix less than a month before the Games.
The Londoner will go head to head with the man who beat him to the world title in Daegu last year at Crystal Palace on July 14.
The pair have already met this season, with Idowu beating the 21-year-old American in last Saturday's Diamond League meeting in atrocious conditions in Shanghai.
"I've got a good winter of quality training under my belt and now I'm aiming for the gold medal," said Idowu, who jumped 17.24 metres on his first outing of the season in China.
"The Aviva London Grand Prix is only three weeks before we jump at the Olympics, so it's perfect for me to keep sharp and get the support of the home crowd which will give me a taste of things to come in the Olympic stadium.
"I'm looking forward to taking on the best jumpers in the world on July 14th. I'm never one to avoid my main competitors.
"We have all had some great battles in previous years but if I go out there and execute at Crystal Palace, I'm confident that it will give me a boost towards competing at the Games."
Taylor, who took gold at the World Championships with a leap of 17.96m, 15cm further than Idowu has ever jumped, said: "It's a great way for me to prepare for the Olympics a few weeks later."
The American, who also beat Idowu at last year's London Grand Prix, insists he will not underestimate his rivals.
He said: "It was nice to beat Phillips in his home town, but I know what he's capable of and I know he's never to be underestimated. We're both elite jumpers capable of big distances so it comes down to who steps up on the day and who shows the most heart."
