Great Britain won a third triathlon medal at the Paris 2024 Olympics on Monday after a dramatic finish to an exhilarating mixed relay race.

GB initially thought they had won silver in a photo finish, but it was later downgraded to bronze.

Simone Biles’ ‘redemption tour’ continued and the American superstar reminded fans she is not invincible during the women’s balance beam final.

GB pair Molly Caudery and Holly Bradshaw were in tears after suffering surprise exits in pole vault qualifying.

But there have been plenty of positives for the team so far in the athletics, while sport climbing also got under way on day 10.

After Alex Yee won the men’s triathlon race and Beth Potter claimed bronze in the women’s, GB had high hopes for Monday’s mixed relay.

They led narrowly for much of the first three legs – featuring Yee, Georgia Taylor-Brown and Sam Dickinson – with Potter having a five-second advantage as she began the anchor leg.

Potter was caught on the bike by Germany’s Laura Lindemann and the USA’s Taylor Knibb, before battling to stay with them during the run, and she was fractionally third as the trio turned into the home straight and sprinted for the line.

Lindemann held on for gold and although Potter and Knibb had the same time, the USA were given silver after officials reviewed the finish-line photo.

Simone Biles has already won three gold medals at these Games – in the team, all-around and vault events.

But China’s Zhou Yaqin was the top qualifier for the balance beam final and Biles fell off the beam to miss out on a medal for the first time in Paris.

The American, 27, lost her balance at the end of an aerial series and placed fifth, in a final where half of the gymnasts fell off the 10cm-wide apparatus.

Italy’s Alice D’Amato won gold, with team-mate Manila Esposito third while Zhou took silver.

Biles looked unhappy with the crowd after her routine, speaking animatedly to her coach and team-mate Sunisa Lee, but has one more chance for another medal in the floor final (from 13:23 BST).

GB also had high hopes for the women’s pole vault, with Holly Bradshaw winning bronze at Tokyo 2020 and Molly Caudery becoming world indoor champion in March.

Caudery, 24, has the world’s highest jump of the year having set a British record of 4.92m in June.

But her first Olympics were shortlived as she failed with three attempts to clear 4.55m at the Stade de France.

Bradshaw also crashed out as although she got a 4.20m on the board, she then failed to clear 4.40m.

On a busy morning in the athletics, Alastair Chalmers made a desperate dive for the line to ensure he qualified for the semi-finals of the men’s 400m hurdles, while defending champion Karsten Warholm won his heat.

Jessie Knight also made a late lunge for the line in the women’s 400m hurdles to join GB team-mate Lina Nielsen in Tuesday’s semi-finals.

Lina’s twin sister Laviai qualified for the women’s 400m semi-finals and Amber Anning won her heat, although Victoria Ohuruogu must go through to the repechage round.

However, both Lawrence Okoye and Nick Percy failed to qualify for the men’s discus final.

The men’s 200m heats begin later (18:55 BST), although GB’s Zharnel Hughes has withdrawn because of tightness in his hamstring.

The women’s 200m semi-finals take place from 19:45 and GB’s Keely Hodgkinson will go for gold in the women’s 800m final at 20:47.

Sport climbing got off to an exciting start in Saint-Denis with two British climbers in contention in the men’s combined event.

Toby Roberts, 19, is ranked third after the boulder semi-final, scoring 54.1 at Le Bourget sport climbing venue.

Hamish McArthur, 23, is also well placed as his score of 34.2 leaves him in eighth heading into the lead semi-final on Wednesday.

The top eight after Wednesday’s session will qualify for Friday’s final.
