Grubla Trail - 2° Trail dei Castellieri

Grubla Trail - 2° Trail dei Castellieri is a trail running race held in June. The name indicates it is the second edition of the Trail dei Castellieri, and the event is listed on ENDU under both trail and running categories. The available event page provides practical information rather than extensive narrative. It directs runners to registration, venue details, media, and results via ENDU. With only a second edition noted, this suggests a developing trail race establishing its identity, rather than an established event with a long public history.
