Mo Farah returns to action on Thursday for the first time since doping claims against his coach Alberto Salazar.
The double Olympic champion, who says he is "100% clean", faces Great Britain team-mate Andy Vernon in the Diamond League 5,000m in Lausanne (20:00 BST).
Farah will race against five of the top six in the world rankings this year.
Six-time Olympic champion Usain Bolt misses the 100m, but Justin Gatlin, Asafa Powell and Tyson Gay are set to line up in Switzerland.
Farah, 32, will be running over 5,000m for the first time this season in what will be his first race for six weeks.
He pulled out of a Diamond League meeting in Birmingham last month following claims made by BBC Panorama and US investigative website ProPublica that Salazar violated several anti-doping rules.
Salazar has denied the allegations and issued a 12,000-word document refuting claims made in the investigation.
Farah has not been accused of any wrongdoing and has welcomed subsequent investigations by UK Anti-Doping and the US Anti-Doping Agency.
On Thursday he will face Vernon for the first time since the pair had a row on social media.
After Lausanne, Farah is due to race over 1,500m in Monaco eight days later before returning to the Olympic Stadium in London to compete in the 3,000m at the Anniversary Games the following week.
