The 2017 IAAF Diamond League was the eighth season of the annual series of outdoor track and field meetings, organised by the International Association of Athletics Federations (IAAF).
It is the first to feature the new championship-style system in which overall event winners are determined only by the results of the final meet.
The Diamond League's format was completely overhauled for the 2017 edition.
The Diamond Race system used in previous years, in which athletes accumulated points through the season with double points in the finals, was replaced with a championship-style format in which earlier meets act as qualifying meets for the finals; the top eight or twelve athletes, depending on the event, will qualify.
[1][2] The two final meetings are held at the end of the season in Zürich (Weltklasse) and Brussels (Memorial Van Damme), with half of the 32 events contested in each final; the overall Diamond League championship in each event will be determined solely by the results of the finals.
[3] While not previously used in the Diamond League, this new system is similar to the old IAAF Grand Prix circuit with its IAAF Grand Prix Final.
[4] Scoring in the non-final meets was extended from the top six to the top eight, with the winner receiving eight points and the runner-up seven, down to one point for an eighth-place finish.
[1] Instead of all 32 events appearing in six meets and the final, half of the events now appear in only four qualifying meets in addition to the final; the remaining events are still contested in six qualifying meets and the final.
[3][5] A controversial field event rule change from 2016, under which only the top four athletes after three rounds were allowed the full six attempts, was reverted for 2017.
[1] The following fourteen meetings are scheduled to be included in the 2017 season:[6] Top 8 qualified as of right.
