What is K3 ULTRA
K3 ULTRA – GOLD BORDER RACE is the first ultramarathon whose routes cover Bulgaria’s borderline part of the Rhodopes.
The event takes place at the end of September – the most colourful and picturesque month of autumn.
The finishing line of the K3 ULTRA – GOLD BORDER RACE is in the country’s southernmost and magnetic town – Zlatograd.
The ultramarathon offers several distances.
The marathon routes alternate between breathtaking views and adrenaline-pumping sections.
These include a climb to the medieval Kechi Kaya Fortress and the chapels of St. Athanasius, St. Nedelya, St. Ekaterina and other historical and natural attractions.
The routes also reveal 360-degree views of the magnificence of the Rhodopes in some places, and in others – the runners will have the opportunity to enjoy a panorama of both Bulgaria and neighbouring Greece.
