The Wanda Diamond League is athletics' premier one-day series. The competition encompasses 15 of the sport's most prestigious one-day meetings, with men and women competing in 16 of its primary disciplines. Athletes compete for points at 14 series meetings from May to September, with the most successful in each discipline qualifying for the Wanda Diamond League Final in Eugene (September 16th-17th).
At each of the 14 series meetings, athletes are awarded 8, 7, 6, 5, 4, 3, 2 or 1 points for ranking 1st to 8th respectively. The top six in the field events, top eight for 100m-800m and the top ten for 1500m and long distance events will qualify for the Final. In case of a tie, the athlete with the best legal performance of the season is ranked higher.
Those who have qualified compete in a winner-takes-all competition at the final to be crowned Wanda Diamond League Champion in their chosen discipline. In each discipline, one athlete may also qualify via national or global wildcard.
All 32 Diamond League Champions (one man and one woman in each of the 16 disciplines) are crowned over two days of athletics action at the Prefontaine Classic in Eugene. Each champion is awarded a prestigious "Diamond Trophy", US$ 30'000 prize money and a wild card for the World Athletics Championships (certain conditions apply).
The new Final 3 format is used in the throws and horizontal jumps at all series meetings, but not at the Wanda Diamond League Final.
