History of the Quebrantahuesos Gran Fondo
The Quebrantahuesos Gran Fondo has been a staple of the European amateur cycling calendar since 1991, when the first edition took place in the small town of Sabiñánigo, Spain. The event was the brainchild of Peña Ciclista Edelweiss, a local cycling club with a passion for mountainous routes and grand challenges. What started as a modest event for regional cyclists quickly grew into an international phenomenon.
By the late 1990s, participation numbers surged, and the event began attracting riders from all over Europe and beyond. Its combination of professional-level organization, scenic alpine routes, and steep ascents soon gave it a reputation comparable to Italian and French counterparts like the Maratona dles Dolomites or the Étape du Tour.
Today, the Quebrantahuesos is not only a flagship event on the Spanish cycling calendar but also part of the UCI Gran Fondo World Series, further cementing its status as a world-class long-distance cycling challenge.
Location of the Event
The Quebrantahuesos takes place in Sabiñánigo, a small town in the province of Huesca, nestled in the Aragonese Pyrenees of northern Spain. Sabiñánigo provides the perfect base for mountain cycling, with direct access to several of the Pyrenees’ most famous passes. Its location near the French border also allows the route to dip into southern France, adding an international flair to the event.
The surrounding terrain is dramatic and varied, featuring everything from winding forest roads to high-altitude mountain passes. Riders are treated to sweeping vistas, historic villages, and open plateaus that make the physical challenge worth every pedal stroke. Moreover, the area enjoys a strong cycling culture, with local spectators lining the route in support of participants.
Logistically, Sabiñánigo is well-equipped for large sporting events, offering ample accommodations, support services, and access via road and rail from major Spanish cities like Zaragoza and Barcelona.
