The sixth edition of the Bizkaia Kopa Trail series features its latest installment, an exhilarating mountain race spread across six stages throughout the year. This popular trail running league offers both competitive and non-competitive options to cater to runners of all levels. For those looking for a leisurely adventure in nature, there are two walking categories: Mountain Walk 10K and Mountain Walk 20K. These routes wind through picturesque landscapes, offering participants an opportunity to enjoy the stunning scenery at their own pace while taking in the beauty of the Basque countryside. Competitors aiming for more challenging terrain can choose from three race options that count towards individual rankings (men's, women's, veterans' and veteran women’s categories) as well as team standings. The Trail 10K and Trail 20K courses are designed to test endurance against varied terrains, with steep climbs and scenic descents providing a thrilling experience for trail runners. Additionally, the Txakurkros event adds an element of excitement by incorporating elements specific to Basque culture into its course design. This unique race is not only physically demanding but also offers cultural immersion through themed checkpoints along the route. Registration opens during the week leading up to each stage; however, participants who sign up at this time will miss out on any complimentary gifts usually provided with early registration.
