Great Britain's Keely Hodgkinson was forced to settle for silver in a pulsating women's 800m final on the final day of the 2022 World Athletics Championships in Eugene.
The Tokyo 2020 runner-up was involved in a two-horse race with Athing Mu of the USA for the world title and just missed out on the gold with a time of 1:56.38.
Mu just edged out the Brit with a world-leading time of 1:56.30 to finish on top of the podium, with Hodgkinson visibly disappointed after the race.
"This year all I had on my mind was the gold. It definitely shows the expectations I've got for myself. I gave it everything right up to the line, so close!" Hodgkinson told BBC Sport.
"I'm definitely a little bit annoyed but being on another world podium in my second year of being in the professional world of athletics is something I should be proud of.
"I am a bit gutted, but to be gutted with a world medal just shows how far I've come. I've got a lot more to work on and we've got world champs next year so I can't dwell too much.

"Unfortunately, it wasn't good enough this time but the gap's closing and hopefully one day I'll get there. I took the shortest route. I sat in, bided my time. I was confident. I don't think I did anything wrong, it just wasn't my time."
Meanwhile, the Championships closed with the women's 4x400m relay final, during which GB won their seventh and final medal of the 2022 tournament with a hard-fought bronze.
The team of Victoria Ohuruogu, Nicole Yeargin, Jessie Knight and Laviai Nielsen finished with 3:22.64 to take a spot on the podium behind the USA (3:17.79) and Jamaica (3:20.74).
With one gold, one silver and five bronze medals, GB placed 11th in the overall medal table, as a dominant USA led the way with 33 on home soil.
Elsewhere on the final day, a new world record was set in the men's pole vault by Sweden's Armand Duplantis, who cleared the 6.21m mark on his way to the gold medal.
Duplantis broke his own world record of 6.20m, which he set indoors in Belgrade in March, as second-placed Christopher Nilsen posted a best score of 5.94m.
