Jurajskie Mistrzostwa na Skraju Przelaju

Jurajskie Mistrzostwa "Na skraju przełaju" is a trail-running event in Przewodziszowice, Poland, organized by ExtremeJura as part of the Jurajskie Mistrzostwa series. It focuses on Jura cross-country running, not road racing, and offers four distances: 7 km, a quarter marathon, a half marathon, and the 30.5 km Trenteraton. The routes include significant climbing for their distances: approximately 200 meters for the 7 km course, 300 meters for the quarter marathon, 500 meters for the half marathon, and 550 meters for the Trenteraton. The fields are modest, with dozens of participants in each distance, giving it the feel of a local off-road challenge rather than a large-scale race. The shorter 7 km race is named Szczęśliwa 7, and the longest option, the Trenteraton, presents the event's most demanding challenge without reaching ultra distances.
