Boglarka Kapas has become the first woman to win the distance freestyle treble at the European Swimming Championships in London.
Her win helped put Hungary on top of the standings with 10 gold medals during this year's championships.
Kapas held off the fast-finishing defending champion Jazmin Carlin to add the 400m freestyle to the 800m and 1500m titles, making history in the process.
Her achievements had echoes of Katie Ledecky, the American who won all the freestyle titles from 200m upwards at last year's world championships and who has taken the sport into uncharted territory.
Kapas was stunned to have made history. "Oh my goodness! I didn't know that, that's amazing. I am just so happy with today," she told AFP.
It saw the 23-year-old leave with four golds from four events, having also been part of the victorious Hungarian 4x200m freestyle relay as she commanded some of the spotlight reserved for teammate Katinka Hosszu, winner of four golds and a silver.
David Verraszto successfully defended his 400m individual medley title while Laszlo Cseh finished with four medals, including the 100m and 200m butterfly double, as Hungary's swimmers continued their fine tradition in the pool.
Kapas led from the 100m mark to set a personal best of 4mins 3.47secs despite Carlin making inroads on the last length, with Mireia Belmonte in third.
Verraszto moved ahead of the field on the backstroke leg as he defended his 400m individual medley title in 4:13.15 ahead of Slovakia's Richard Nagy and Federico Turrini of Italy.
Hosts Great Britain were second behind Hungary with a total of 22 medals including seven golds, after they won both the men's and women's medley relays in the final two events of the evening.
