Above Pusztafalu, this is trail running in nature and mountains, with UTMB Index courses rather than a town-loop outing. Zempléni Terep Kupa has a practical trail-race feel: pick your distance, then head for the hills.
The long course is named Nagy Hársas Ultra and comes with serious climbing, while Szurok-hegyi Sky sounds like the sharper option when you want your legs to know they have been up something. Expect dirt, gradients, and the sort of field that shows up for mountain running because they actually like earning the finish line, not because it is easy to cruise.
