What to expect from the GBR 63K adventure?
The runners in the K3 Ultra GBR 63K race will start from the centre of Nedelino before beginning the ascent towards the Belite Kamani area above the village of Startsevo, where they will be able to enjoy breathtaking 360-degree views. The route then continues with a gradual climb towards Shadiitsa, offering views to the north of the familiar peaks of Rozhen, Snezhanka and Perelik, and to the south of the ridge along Bulgaria’s southern border, including Lomska Chuka and Veykata peaks. It then descends towards the Pechinsko Aid Station.
From Pechinsko, the runners will follow a pleasant trail through a deciduous forest and pass through the beautiful village of Borinovo before reaching the town of Madan, where they will be welcomed as long-awaited guests.
From the centre of Madan, after a short run through the streets of the town, the runners will take a trail leading to the “sunny” village of Maglishta. From there, the route will run almost entirely above the so-called Madan Ore Field, where they will be able to see both unique mineral formations and specialised mining infrastructure. They will pass beneath the remarkable aerial cableway and reach one of the most impressive rock formations in the Rhodopes – Kechi Kaya, around which the remains of the important medieval Koznik Fortress can still be seen. An aid station offering traditional Rhodopean delicacies from the Madan region will be set up here.
The route then passes by Babkata and continues through a remarkable beech forest to the Marzyan Aid Station. From there, the runners continue directly along the border. Looking south, they can admire the Rhodopes in neighbouring Greece, and in clear weather they may even see the peaks of Samothrace Island, which rise to more than 1,600 metres. To the east lies the beautiful valley of the Varbitsa River.
The route then continues once again along the mountain ridge before descending towards the village of Alamovtsi, where another aid station will be located. From there, the runners climb back to the ridge, passing by Rupchevo Peak, the Kilovi Kolibi area and Kosora Peak. They then descend to St. Ekaterina Chapel.
From there, only two kilometres remain to the finish line in Zlatograd, along a section shared by all race distances.
Great things happen when people and mountains meet!
