Rudisha said Wednesday he will "try and see if it's possible" to run faster than the 1 minute, 40.91 seconds he set at the London Olympics when he competes at the Weltklasse Diamond League meet in Zurich (, 2 p.m. ET).

"That's what I'm looking for. This being my last race of the season, I think I just want to give my best," the 23-year-old Kenyan said.

Rudisha led throughout his Olympic victory three weeks ago but will use training partner Sammy Tangui to pace him through the first 400 on Thursday.

"The last lap I do it myself," said Rudisha, whose first appearance since winning the gold medal will be just his 11th competitive race this year. "Every race is important in our season and we always want to do the best every time."

That selective program was designed with Rudisha's coach, an Irish missionary based in Kenya who has come to Zurich to see the race.

"After what he did in London without a pace-setter, you wonder if he really needs one," coach Colm O'Connell said.

O'Connell described Rudisha as a "great student" of the 800 who has analyzed how previous record holders Sebastian Coe and Wilson Kipketer ran their races.

At Zurich in 1997, Kipketer set the second of his three world record times, a 1:41.24 run, just weeks after lowering Coe's mark of 1:41.73 which had stood for 16 years. Kipketer's 13-year reign was ended by Rudisha in 2010.

Still, the Swiss weather could harm Rudisha's chances at the sold-out Letzigrund stadium with rain and 15-degree (61 Fahrenheit) temperatures forecast.

"The weather plays a very big role," acknowledged Rudisha, who won his two previous appearances at Zurich. "I have run very few races in the raining and the cold."

Bolt, Blake in action

The star-studded Zurich event also features Usain Bolt in the men's 200 metres and Yohan Blake in the 100.

The men's shot put season finale was held on Wednesday ,and defending Diamond League champion Dylan Armstrong of Kamloops, B.C., finished fourth, behind Americans Reese Hoffa and Ryan Whitting and Polish Olympic gold medallist Tomasz Majewski.

Hoffa captured the season title by a wide margin, while Majewski finished second and Armstrong third.

On the women's side, Thursday's 100m race is loaded with big names like Olympic gold medallist Shelly-Ann Fraser-Price, runner-up Carmelina Jeter, and American star Allyson Felix.

Canadians Jessica Zelinka, Phylicia George and Priscilla Lopes-Schliep will compete in the 100-metre hurdles.
