National teams will be permitted for the first time to display the logo of a sponsor on their kit at the International Association of Athletics Federations (IAAF) World Championships, starting next year with the latest edition in Doha - for which qualifying standards have been announced.
"We only have really big global moments every two years," said IAAF President Sebastian Coe.
"We have to absolutely maximize every bit of financial potential in our sport through those venues, and we wanted this to be a much more equitable process."
The IAAF confirmed that, following a two-day meeting of its ruling Council here, the performance standards agreed for next year’s World Championships, which will run from September 28 to October 6, are similar to those used for the 2017 edition in London, there are "two notable differences".
Firstly, target numbers have been introduced for the road events and 10,000 meters races - 100 for marathons, 60 for the 20 kilometers race walks, 50 for the men's 50km race walk and 30 for the women's, and 27 for the 10,000m.
