Bytom

Bytom sits in the heart of Poland's Upper Silesia, a postindustrial region with flat to gently rolling terrain around 270m elevation. The local cycling scene centres on region-wide events like Rowerowy Rajd Nadziei and the epic 390km Tour De GZM II Ultramaraton Rowerowy, which draw riders through the Silesian landscape; runners find the flat ground suited to steady efforts, with the Cross Duathlon anchoring the local multisport calendar.
