The women's 400 metres event at the 2017 European Athletics U23 Championships was held in Bydgoszcz, Poland, at Zdzisław Krzyszkowiak Stadium on 14 and 15 July.
The 400 metres, or 400 metre dash, is a sprinting event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440 yard dash (402.336 m)—which is a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete.
The 2017 European Athletics U23 Championships is the 11th edition of the biennial athletics competition between European athletes under the age of twenty-three. It is held in Bydgoszcz, Poland from 13 to 16 July. This is the second time that the competition is being hosted by Bydgoszcz after the 2003 edition.
Bydgoszcz is a city in northern Poland, on the Brda and Vistula rivers. With a city population of 358,614, and an urban agglomeration with more than 470,000 inhabitants, Bydgoszcz is the eighth-largest city in Poland. It has been the seat of Bydgoszcz County and the co-capital, with Toruń, of the Kuyavian-Pomeranian Voivodeship since 1999. Prior to this, between 1947 and 1998, it was the capital of the Bydgoszcz Voivodeship, and before that, of the Pomeranian Voivodeship between 1945 and 1947.
