Two-time Olympic marathon champion Eliud Kipchoge will take on members of the public in a running challenge to mark 1,000 days until the start of the Paris 2024 Games.
The Kenyan will participate in a pursuit-style 5km race against 2,000 runners on the Champs-Elysees in the French capital on 31 October.
Kipchoge holds the world record for the marathon, running 2:01:39 at the Berlin marathon in 2018, and defended his Olympic title in Tokyo in August.
“I am delighted to be heading to Paris 1,000 days before the start of the 2024 Olympic Games for a truly exceptional challenge,” he said.
