The phrase “2015 Speedway Grand Prix of Poland III” does not correspond to a widely recognized or documented event in the official records of the Speedway Grand Prix series. In the 2015 season, the Grand Prix calendar included two Polish rounds: the 2015 Speedway Grand Prix of Poland held in Gorzów Wielkopolski (June) and the 2015 Warsaw Speedway Grand Prix (September). No authoritative sources list a third (III) Polish Grand Prix for that year.
Given the absence of reliable encyclopedic references, the term remains unverified and is not considered an established concept within the sport’s historical documentation. Any further interpretation would be speculative.
