Poland’s defending champion Karolina Kucharczyk added five centimetres to her own five-year-old world mark in the women’s long jump T20 event as she took gold with an effort of 6.14 metres at the Friedrich-Ludwig-Jahn Sportpark.

Erica Gomes of Portugal took silver and bronze went to Croatia's Mikela Ristoski.

Back in action after the birth of her son last year, Kucharczyk, who missed the London 2017 World Championships, was more determined than ever to make her mark in the German capital.

“I was prepared to beat the world record, I was even prepared to jump 6.20m,” said Kucharczyk after earning Poland's 13th gold medal of the Championships.

“Last year my son was born, so I told myself I must come back stronger - I must prove to myself that I am stronger than before. 

"I’ve been training so hard to jump a world record here and I dedicate my world record here to my son.

“It was very important for me because I felt my rivals’ breath on my neck. 

"I know they are coming, so I knew I had to make my record further just to be at least half a metre in front of them.”

Just over nine hours later, home athlete Birgit Kober registered world record number two for the day as she achieved a distance of 11.79m in the women’s shot put F36/37 category.

Eva Datinska of the Czech Republic was the recipient of the silver medal, while bronze was claimed by Juliane Mogge of Germany.

In the last event of the day, Ukraine's Zoia Ovsii also broke the world mark as she registered 24.31m in the women's club throw F51 final.

Joanna Butterfield of Britain clinched silver and no bronze was awarded as there were only three entrants.

There were other towering achievements in the form of a European record and nine Championship records.

The European record went to Tomasz Paulinski of Poland, who won the men’s shot put F34 final with 11.00m.

Championship records fell at regular intervals on a high-quality day of athletics.

The first didn’t even require a final as Timothee Adolphe of France won his men’s 200 metres T11 heat in 23.21sec.

That effort was closely followed by victory in the men’s javelin throw F54 by Aliaksandr Tryputs of Belarus, who threw 29.48m.

Poland’s Piotr Kosewicz, who won the men’s discus throw F52 final with 20.20m, and his compatriot Marta Piotrowska, who took the women’s long jump T37 title with 4.51m, were the next to add to the championship record list.

Ukraine, who have had a lot of success at these Championships, were the next to contribute as Mykyta Senyk won the men’s long jump T38 final with 6.25m, and then compatriot Leilia Adzhametova took the women’s 100m T13 title in 11.93.

Belgium were next, as Peter Genyn won the men’s 200m T51 final in 42.26.

The last two Championship records of the day came in the sprints, as hosts Germany won the men’s 4x100 relay T42-47/61-64 in 41.42sec, and then Finland’s Leo Pekka Tahti won his men’s 100m T54 heat in 14.08sec.
