The 16th season of the Diamond League is underway as the Athletics Olympic stars build their opportunity for world glory in 2025.
Athletes compete for points in 32 disciplines in an attempt to qualify for the finals in Zurich in August.
That takes almost a fortnight before the start of the World Athletics Championship in Tokyo, Japan.
All the events of the Diamond League will be shown, which has an agreement to transmit the competition over the next five years.
It is also the first year in which the Diamond League must compete with the new Grand Slam track by Michael Johnson for athletes.
However, there is one leg, only a direct clash between the two competitions, with the Miami Slam on 2-4 can take place at the same time as the match in Keqiao, China, on May 3.
The Diamond League has increased its award in money at the highest level in its history, with a total award of $ 9.24 million (£ 6.95 million) in sacross the series.
That includes $ 500,000 (£ 375,000) in each of the 14 series meetings and $ 2.2 million (£ 1.7 million) in the Diamond League final.
