2020–21 ISU Challenger Series
The 2020–21 ISU Challenger Series was scheduled to be held from September 9 to December 5, 2020. It was the seventh season that the ISU Challenger Series, a group of senior-level international figure skating competitions, was held. Originally meant to be a series of ten events, the 2020–21 Challenger Series ended up featuring only two individual events, when eight events were cancelled due to the COVID-19 pandemic.
Impact of the COVID-19 pandemic
The International Skating Union announcement on April 22, 2020 for the 2020–21 ISU Challenger Series issued the following caveat regarding the scheduling of the events:On May 1, 2020, the International Skating Union established a working group, chaired by ISU Vice-president for Figure Skating Alexander Lakernik, to monitor the ongoing COVID-19 pandemic. Its responsibilities included determining the feasibility of holding events as scheduled, possibly behind closed doors, during the first half of the season, and the financial impact of any potential cancellations. The ISU announced that a host federation must make a decision regarding potential cancellation of their event at least twelve weeks prior to the event.
On May 16, the Slovak Figure Skating Association informed the ISU that it had cancelled all upcoming events that it was scheduled to host due to the ongoing pandemic, including the 2020 Nepela Memorial in Bratislava.
On July 13, the ISU announced that the 2020–21 Challenger Series events would be regarded as separate individual competitions, rather than as a series; as a result, no Challenger Series ranking would be determined and no prize money would be distributed at the end of the series. However, skaters competing would still earn Challenger Series-level points for their world rankings, as long as the competition met ISU guidelines to qualify as a Challenger event. The decision was later revised by the ISU council on August 3, announcing that world standing and ranking points would not be awarded for the sake of fairness due to the limited nature of the competitions.
On July 13, the Japan Skating Federation announced that it would not assign any skaters to the Challenger Series, assuming the competitions proceeded as scheduled.
On August 25, the German Ice Skating Union confirmed that 2020 Nebelhorn Trophy would be held as scheduled, but without spectators and would include extensive social distancing guidelines and procedures for the athletes and coaches in attendance.
On August 28, the ISU removed the maximum entry limit of skaters or teams per country.
