David Weir called time on his career representing ParalympicsGB following the conclusion of the T54 men’s marathon on Sunday morning.
Weir, 45, finished fifth in the marathon, which was won by Switzerland’s Marcel Hug.
After Weir’s seventh Paralympics came to a close, he retired from GB competition that has included 10 Paralympic medals – six of them gold – after making his Paralympic debut at Atlanta in 1996.
Weir, who is also a six-time world champion, cited the T54 marathon being removed from the World Championship schedule among his reasons for retiring from international competition.
“I knew before I came to Paris and I’ve been thinking about it all week… It’s the right decision,” said Weir.
“We don’t have marathons at Worlds any more. That’s the event I want to do. I don’t want to race on track any more.”
In the women’s T54 marathon, GB’s Eden Rainbow-Cooper did not finish, having completed more than half of the 42.2km course. Switzerland’s Catherine Debrunner won the race to take her sixth medal and fifth gold of the Games.
