Entries comprise 1054 men and 918 women. Of the 44 individual winners from two years ago, 37 will defend their titles in Doha. All 30 of the newly minted Diamond League champions will also be in action.
Some athletes set to compete in Doha will make history.
Allyson Felix, the most decorated athlete in IAAF World Championships history, will have the opportunity of increasing her record tally. The US sprinter has 16 World Championships medals (11 gold, three silver and two bronze) and has been named as part of USA’s 4x400m squad.
When Spanish race walker Jesus Angel Garcia takes to the start line for the 50km race walk on 28 September, not only will the 49-year-old extend his own record number of appearances to 13, but the 1993 world champion will also become the oldest competitor ever to take part in an IAAF World Championships.
Official start lists will become available after the technical meeting on the evening of Thursday 26 September.
