Today the IAAF approved the 2020 Olympic qualifying standards which are going to be the hardest outdoor world championship standards ever.
Athletes will have two ways to qualify:
• Achieve the entry standard within the respective qualification period.
• Qualify by virtue of his/her IAAF World Ranking position in the selected event at the end of the respective qualification period.
The process is designed to achieve about 50 percent of the target numbers for each event through entry standards and the remaining 50 percent through the IAAF world ranking system.
Qualification Period: May 1st 2019 - June 29th 2020 (Jan 2019-May 2020 for Marathon/50km RW)
