ISU Challenger Series

For the current season, see 2025–26 ISU Challenger Series.

The ISU Challenger Series is a series of international figure skating competitions sanctioned by the International Skating Union (ISU) and organized by ISU member nations. The series was introduced in 2014, with the goal of ensuring consistent organization and structure within a series of international competitions linked together, and providing opportunities for senior-level skaters to compete at the international level while also earning ISU World Standing points.^[1]

The ISU Challenger Series Synchronized Skating is a separate competition series in the discipline of synchronized skating.

History

The ISU Council decided to create the series at its February 2014 meeting.^[2] Eleven competitions were selected in June 2014.^[3] The Triglav Trophy dropped out by October 10, 2014, resulting in a series composed of ten events. The Nebelhorn Trophy, Finlandia Trophy, Ondrej Nepela Memorial, and Golden Spin of Zagreb are the "core group".^[4] The event criteria were published in April 2014,^[5] and revised in August 2014.^[6]

The notice on the ISU Challenger Series Synchronized Skating was announced on May 10, 2019, which is for the discipline of synchronized skating and is held separately from the other ISU Challenger Series.^[7]

The Asian Open Classic was planned to be included in the 2019–20 season, but ISU transferred the event holding right back to Asian Open Trophy later.^[8]

In the 2020–21 season, due to the COVID-19 pandemic, it was decided to hold the Challenger competitions as individual events, rather than as a series.^[9] Entry limits per country were also removed.^[10]
