The Diamond League said that it plans to return to a full competition format next year with a complete programme of 32 disciplines if the global health situation allows it.
A new format was introduced for the 2020 season with the number of disciplines brought down to 24 in an effort to create a faster-paced meeting that is more palatable to television viewers but the move was widely criticised.
But the Diamond League said it would reinstate among other events the triple jump, discus, 200m, 3000m steeplechase and 5000m in 2021.
The Diamond League said it hoped to better promote field events by introducing a new format – with a qualifying round and a final – for long jump, triple jump, shot put, javelin and discus.
A total of $7 million in prize money would be awarded over the course of the 2021 season, which would comprise 13 meetings in 12 countries and culminate in a final over two days in Zurich.
