Summarize Timeline Fact Check

The race took place around a course off the coast of Palawan Beach, Sentosa.^[3] It was held on 20 July at 08:00 SGT.^[4]

Germany, Italy, Hungary, France and Australia all allocated female swimmers to the first leg of the relay, which meant those top teams were nearer the back of the race. Thailand's Ratthawit Thammananthachote led from the start of the race and finished the leg in first, while Germany's Celine Rieder was the first woman to reach the changeover.^[1]

Over the second leg, Italy and Hungary both employed a second female swimmer, while Germany and France sent in Oliver Klemet and Marc-Antoine Olivier, respectively. Klemet and Olivier took the lead, and going into the second changeover, France was first, Germany was second, and Australia came third.^[1]

Going into the third leg, Inès Delacroix took over for France, Isabel Gose took over for Germany, and Moesha Johnson took over for Australia around 37 seconds behind. Over the third leg, Gose took the lead for Germany, and she had built a nine-second lead over Delacroix by the changeover.^[1][5] France retained second place, and Italy came in third, about one second behind.^[1]

Florian Wellbrock took over for Germany while Gregorio Paltrinieri took over for Italy. Paltrinieri quickly closed the nine-second gap on Wellbrock, while France's Logan Fontaine, Hungary's Dávid Betlehem, and Australia's Kyle Lee followed. Over the final straight, Wellbrock sped up and blocked Paltrinieri to win gold for Germany with a time of 1:09:13.3. Paltrinieri finished second for Italy with 1:09:15.4, and then Betlehem closed for Hungary with 1:09:16.7.^[1] France finished fourth with 1:09:24.7.^[5] After the race, Wellbrock needed medical attention due to the heat of the water.^[6]

Germany's victory earned Wellbrock his fourth gold medal of the Championships, meaning he had won every gold available in the open water events (the 10 km, 5 km, 3 km knockout sprint, and this relay).^[5][7][8] It was the first time this had ever been achieved at the World Aquatics Championships.^[9][10] After the race, Wellbrock said "I'm still speechless. I have no idea how I did it."^[10] On the women's side, Ginevra Taddeucci won silver in the same four events.^[11]

The win also gave Wellbrock his fourteenth world championship medal and tenth gold medal, and Paltrinieri's silver was his nineteenth world championship medal.^[5]
