Festiwal Biegowy Ultra Way w Blasku Ksiezyca 100 Km

Ultra Way's W Blasku Księżyca is a trail ultramarathon exceeding 100 km in northern Poland, centered near Gdynia and organized as part of the Ultra Way Running Festival. The name translates to “In the Moonlight,” reflecting the race's timing: it begins from Puck's Old Market Square in the evening, granting participants 20 hours to complete approximately 103.76 km with about 3,538 m of elevation gain and loss. The event holds ITRA 4-point status and qualifies for UTMB 100K. The festival structure offers participants multiple long-distance options instead of a single race. The premier event, Gwiazda Północy, commences in Wejherowo and extends over 160 km with 4,481 m of elevation change. Another option, Energa O Poranku, begins near Gdynia's seaside promenade for a route over 50 km with 2,158 m of elevation change. Multiple races conclude at Gdyńskie Centrum Sportu, the National Rugby Stadium in Gdynia. Buses transport runners of the longer distances from this sports complex to their respective starting locations.
