The Chilean capital will take the place of San Juan, the capital of the Argentine province of the same name, which had been chosen to host the 2022 edition. 

Economic reasons led to the withdrawal of the organisers, while Argentina's withdrawal was echoed by neighbouring Chile.

As a result, the UCI has confirmed that the event will be held at the Peñalolén Velodrome from 15-19 October 2025. The change of venue was initiated by the National Olympic Committee of Chile, the Chilean Cycling Federation and the neighbouring country's Ministry of Sport.

Inaugurated in 2014 for the South American Games and with a capacity of 3,000 spectators, it has already hosted other international competitions, including the 2015 Pan American Track Cycling Championships, a Tissot UCI Track Cycling World Cup event in 2017-2018 and the track cycling events of the 2023 Pan American Games.

It will be the first time that South America has hosted the event since it was held in Cali, Colombia, from 26 February to 2 March 2014.

The World Championships are held every year in various disciplines and distances of track cycling. Cyclists compete as representatives of their countries.

Following the Paris 2024 Olympic and Paralympic Games, the 121st Track Cycling World Championships will be held in Ballerup, Denmark, from 16-20 October 2024, and in Shanghai, China, in 2026. 

In 2027, they will return to Europe when they are held in Haute-Savoie, France, always under the organisation of the UCI and the local federation.

The event, which will finally be held in Santiago, Chile, is expected to attract nearly 400 athletes from more than 45 countries, according to official forecasts. The World Athletics Championships are the oldest of the disciplines, with the first edition taking place in 1893.
