Usain Bolt says he will not try to break the 200m world record at the Diamond League meeting in Lausanne.
The six-time Olympic champion heads a field of 19 London 2012 gold medallists at the Pontaise Stadium on Thursday.
Bolt will race against compatriots Warren Weir, Jason Young and Nickel Ashmeade and the USA's Wallace Spearmon in the 200m.
"I am not worried about world records right now - I am just trying to get through the season," said the Jamaican.
Bolt is the current 200m world record holder, with a time of 19.19 seconds in the 2009 World Championship final in Berlin, but he does not expect to come close to that mark in Lausanne.
"It can be one of those tracks (to break world records), in great shape and in great weather," he said. "But I'm just trying to end this season injury-free, because it has been a stressful season for me.
"I am just trying to get through these last three races."
Triple Olympic medallist Yohan Blake takes on the USA's Tyson Gay, who finished fourth in the Olympic 100m final, and Ryan Bailey in the 100m in Lausanne.
Olympic 100m bronze medallist Justin Gatlin was also due to compete in Lausanne but withdrew on Wednesday with a stomach problem.
A total of 52 medallists from London 2012 have been entered for the 11th leg of the Diamond League.
All three medal winners from the men's 400m in London will feature, with Olympic champion Kirani James taking on runner-up Luguelin Santos and third-placed Lalonde Gordon. Great Britain's Martyn Rooney and Conrad Williams are also competing.
GB's Olympic high jump bronze medallist Robbie Grabarz will face Russian Ivan Ukhov, who won gold in London.
In the women's events, 100m medallists Shelly-Ann Fraser-Pryce, Carmelita Jeter and Veronica Campbell-Brown are all competing.
The penultimate Diamond League meeting takes place in Zurich on 30 August, with the final event in Brussels on 7 September.
