The start area for Bieg Oko w Oko z Rakiem is located by the National Institute of Oncology in Gliwice, Poland, indicating the day's purpose from the outset. This May charity event, organized by Fundacja Oko w Oko z Rakiem, includes both runners and Nordic walkers. The race supports individuals undergoing or recovering from oncological treatment, with practical aims including patient assistance, cancer prevention education, health awareness, and promoting physical activity. A flexible "Run, Walk As Much As You Want" option is available for those preferring a non-competitive, untimed participation.
The marked routes navigate park paths near the institute and a closed portion of Wybrzeże Armii Krajowej street, with volunteers providing direction. A diverse field participates: runners, walkers with poles, volunteers, families, and individuals focused on contributing rather than achieving a specific time; one edition saw almost 1,500 attendees despite cold rain. Health stands offer self-examination demonstrations on phantoms and consultations with specialists like a physiotherapist, cosmetologist, coach, and psychologist. The event also features a healthy food stall, children's activities, and occasional concerts, functioning as a community fundraiser and prevention awareness event alongside the race.
