Bieg Pamieci Dywizjonu 303 takes place in July in Stara Wies near Borki. The race features distances mirroring the squadron number: 3.303 km, 5.303 km, and 11.303 km. The 5.303 km distance is designated for Nordic Walking, with the other two distances for running. Stowarzyszenie Nasza Wspolna Sprawa is the organizer. The event includes age categories, a limit of 400 participants, and reduced entry fees for residents of Borki municipality, as well as for younger and older participants.
The race commemorates the Polish pilots of Squadron 303, who served in the British Royal Air Force during World War II. Runners in the longest distance begin first, followed by participants in the shorter running distances, and then the Nordic Walking group. The route is available in GPX format for participants to review beforehand. This is a small, local event, and the squadron theme provides a rationale for the unique distance options.
