It is part of a collaboration with SuperHalfs, who runs the half marathon series consisting of the five races.

Latvia's capital is set to host the Championships on September 30 and October 1 and is expecting runners from at least 100 countries to the event.

"Riga is incredibly fortunate not only to host the inaugural World Athletics Road Running Championships and mass races, but also to offer runners the opportunity to take part in three mass races over the championships weekend - half marathon, 5 kilometres, and road mile," said Sašo Belovski, managing director of SuperHalfs.

"At SuperHalfs, we are all about encouraging runners to participate in beautiful running adventures, and the World Athletics Road Running Championships in Riga will undoubtedly be a truly unique and unmissable experience in 2023."

SuperHalfs was created in 2020, bringing all five half marathon races under one umbrella to promote the events together.

"The biggest challenge for us as the organisers of the inaugural World Athletics Road Running Championships is to help recreational runners realise and get used to the idea that anybody can participate in a mass race at the World Championships," said Aigars Nords, head of the Riga 2023 Organising Committee. 

"We believe that our collaboration with SuperHalfs will help us get this message across Europe and the whole world, and persuade running enthusiasts to come and test themselves in Riga in 2023."

There will be a children's festival too at the Championships, who will be able to compete in the mile.
