Blodomloppet Hudiksvall is a community fitness race held at Glysisvallen in Hudiksvall. Participants can choose to walk, jog, or run either 5 km or 10 km. Both distances are timed. Children have a separate option with Lilla Blodomloppet. The race focuses on a specific cause: raising awareness for blood donation.
Strands IF Friidrott organizes this local event in cooperation with GeBlod Gävleborg. The format is suitable for individuals, families, workplace groups, and teams, with options for group registration. Following the race, participants traditionally share a picnic, providing a social conclusion to the day.
