ISU Challenger Series
The ISU Challenger Series is a series of ten international figure skating competitions sanctioned by the International Skating Union (ISU) and organized by ISU member nations. The series was introduced in 2014; its goal is to provide opportunities for senior-level skaters to compete at the international level while also earning points towards the World Standings and Season's World Ranking. The Nebelhorn Trophy, the Nepela Memorial, and the Golden Spin of Zagreb have been regular competitions in the series since the beginning, as was the Finlandia Trophy until 2024. Skaters and teams are eligible to compete in up to three Challenger Series events each season, and their top two scores are combined to calculate their total Challenger Series scores.
