ZURICH, Switzerland (AP) — Usain Bolt aims to achieve greatness with a third Olympic triple gold-medal haul at the 2016 Rio de Janeiro Games.

“To actually go to Rio and win again would be a feat in itself,” Bolt said yesterday, speaking ahead of the Weltklasse Diamond League meeting.

The Jamaican will run in the 100 metres today after a World Championship sweep in the 100, 200 and 4×100 relay in Moscow, where he talked of working hard to attain “the greatness thing”.

He completed the same triple at the past two Olympics and is focused on repeating in Rio.

“For me, the key thing is just to go to defend my titles, and that’s my focus,” Bolt said. “It would be the first time anybody has ever won three times in a row.”

Bolt became the most decorated athlete in World Championships history this month, with his career tally of eight golds and two silvers lifting him above American great Carl Lewis.

Three more golds for Bolt in Rio would still leave him trailing Lewis’ Olympic track and field record of nine golds and one silver.

“I won’t be adding a fourth event in Rio, for sure,” said the 27-year-old Bolt, whose 34th birthday could fall during the 2020 Summer Games.

Bolt’s news conference was held at FIFA headquarters, across the city from the stadium where he will today.

Bolt was greeted on arrival by FIFA President Sepp Blatter, and later accepted a blue FIFA football shirt bearing his name and the Number 9.

Blatter joked that nine seconds was probably the limit for Bolt, whose 100m world record set in 2009 stands at 9.58.

Bolt suggested he was capable of running in the 9.70s at Weltklasse, where a warm, still evening is forecast.

“I have got a lot of rest,” said Bolt, who last year in cool, wet conditions set a Weltklasse meet record of 19.66 in the 200m. “This track is always a fast track and I’ve run some fast times here.”

He ran a season’s-best 9.77 in Moscow and rivals today include worlds runner-up Justin Gatlin of the United States and Jamaican bronze medallist Nesta Carter.

Though Bolt is the star attraction, the sold-out Letzigrund stadium will also focus on stellar fields for the men’s high jump and women’s 5,000m.

Last month in Switzerland, Bohdan Bondarenko barely failed to clear 2.46 metres at the Athletissima meeting in Lausanne, which would have lifted him above a cherished record in track and field.

Cuban great Javier Sotomayor’s 20-year-old mark of 2.45m survived another challenge by the Ukrainian when taking the world title in Moscow.

“Many people wait for the world record. I can’t just decide when I jump the world record, or I would do it,” said Bondarenko, who looked forward to competing in a more relaxed setting today. “I think this is good because emotions get in the way of jumping.”

Ethiopian rivals Meseret Defar and Tirunesh Dibaba rarely race each other outside of major championships, yet the winners of the past three Olympic titles over 5,000m will clash over that distance in Zurich.

“It’s a prestige-laden race — and yes, it’s very expensive,” said meet director Patrick Magyar, describing his efforts to make the match as perhaps the toughest of his career.

Magyar also accepted Caster Semenya of South Africa, who missed the worlds through injury, into the 800 metres after taking the word of her coach, Maria Mutola, who holds the record for wins at the prestigious Weltklasse meet.

“If Maria tells me Caster is in shape to beat anybody in this race, I have to believe her,” said Magyar, who has a special send-off planned for a retiring American long jump star.

Dwight Phillips, the 2004 Athens Olympics gold medallist and four-time world champion, will compete in his final competition at the age of 35.
