Looking back at 2025: women made up 53% of runners
Donostia Kirola reported that more than 4,000 people took part in 2025 and women made up 53% of the field, the highest share recorded at that time for a mixed 10K in the city. It gives useful context to the event’s reach and women’s participation in local running.
A charitable side with Iñurri
The 2026 race’s charitable connection is with Iñurri, an association that supports people affected by cancer and raises awareness. The race’s official site also describes initiatives that help women who are new to running get started. Check the organiser’s page for the current scope of the partnership and ways to take part.
