Marklowice hosts one event in the LIGA BIKE RACE, a four-round MTB league organized by Fundacja Rozwoju i Sportu BIKE RACE TEAM in Poland's Rybnik and Wodzisław region. The series awards points at each round, affecting riders' rankings throughout the season, with a final general classification after the last event. The Marklowice race has a distinct local character, as it was the first event of its type held in the village.
The league's schedule connects Lyski, Zamysłów, Marklowice, and Racibórz, offering participants multiple distinct off-road races instead of a single standalone competition. The competition includes categories for balance-bike children (Bajtelek), Juniors, Amateurs, Sport riders, and PRO competitors. Completing more rounds is significant, as each start provides an additional opportunity to earn points and improve one's position in the overall standings.
