Granfondo Serra D’Ossa
The 3rd edition of the Granfondo Serra D’Ossa will take place on October 5, 2025, in the historic town of Borba, Alentejo. Organized through a partnership of five municipalities — Alandroal, Borba, Estremoz, Redondo, and Vila Viçosa — the event invites cyclists of all levels to explore the stunning landscapes of Alentejo across three scenic routes: Granfondo, Mediofondo, and Minifondo.
Although non-competitive in nature, the event features electronic chip timing for the full course and/or pre-designated segments. Riders are grouped by category and enjoy the experience at their own pace, with full support along the route.
With scenic roads, regional charm, and a relaxed but festive cycling atmosphere, Granfondo Serra D’Ossa is a must-do for road cycling enthusiasts looking to ride through one of Portugal’s most picturesque regions.
