Competition in the Polish city will take place between July 19 and 21 at the Zdzislaw Krzyszkowiak Stadium, a regular host of major athletics competitions.

It comes after Berlin withdrew as a host this year due to refurbishment work at the Friedrich-Ludwig-Jahn-Sportpark.

A hosting agreement has been signed by Polish Paralympic Committee and Polish Sports Association for the Disabled President Lukasz Szeliga, event director Marcel Jaroslawski and World Para Athletics.

"Para-athletics is the most significant sport in our association," said Szeliga. 

"We are delighted that we have received an offer from World Para Athletics to organise such a big event.

"It is a big challenge but we are extremely happy that our athletes will have the opportunity to compete on their home soil."

Haozhe Gao, head of World Para Athletics, added: "World Para Athletics is delighted that Poland will join the Grand Prix series in such an exciting year that culminates in the 2019 World Championships in November.

"Expanding the Grand Prix series into new territories is great news for the sport and I have no doubt that the event in Poland will be a great success."

Poland topped the medals table at last year's European Para Athletics Championships in Berlin, claiming 26 golds and setting six world records.

The 2016 World Junior Championships is among the major athletics events to have been held in Bydgoszcz.

This year's Grand Prix season began in Dubai last month.

Other legs are due this term in São Paulo, Beijing, Phoenix, Nottwil, Grosseto, Tunis and Paris.
