On October 25, 2025, the 8th edition of the Gaasterland Trail invites runners to explore the tranquil beauty of southwest Friesland—from wooded paths to open heath and historical farmland. Participants can select from multiple trails, including a 10 km, 24 km, and 50 km ultra—all designed to celebrate nature with minimal environmental impact through the “Support for Nature” initiative, which includes a small environmental contribution built into the entry fee. The event prioritizes enjoyment and connection, with un-timed distances that foster a laid-back trail ambiance suitable for both experienced and novice runners. Runners navigate varied, mostly unpaved terrain through Gaasterland’s forests, meadows, heathland, and cultural landscapes.
