Euler jump

The Euler is an edge jump in figure skating. The Euler jump was known as the half loop jump in International Skating Union (ISU) regulations prior to the 2018/19 season when the name was changed.^[1] Its invention has been attributed to both to Carl and Gustav Euler, two Austrian brothers who won the men's pairs competition at the 1900 European Championships,^[2] as well as to Swedish figure skater Per Thorén, who won a bronze medal at the 1908 Olympics in London. It is thus also called the Thorén jump in Europe.^[3] It is also a jump used in artistic roller skating.^[4]

According to U.S. Figure Skating, two benefits of the name change are that it simplifies the notation system for judges and makes it easier for skaters to attempt three-jump combinations, even if single loop jumps are already a planned part of their programs or if they accidentally pop out of a previous loop jump.^[1] A Euler is considered a non-listed jump and is not counted when used in a jump combination between two listed jumps.^[5]

After the 2026—2027 season, the Euler cannot be included in the jump combination during the short program of single skaters and pair skaters, but it is allowed only once during the free skating program when executed between two listed jumps.^[5] According to the ISU, also after the 2026—2027 season, "After the execution of an Euler (half-loop), no change of foot before the next jump is allowed".^[6] When used in combination with two listed jumps, the Euler is counted as a listed jump with a base point value of 0.50 points.^[5][7]
