25 km Deer Trail
25 km - Deer Trail
May 29, 2027 at 09:30 – Kočevje, Slovenia
“The forest won’t ask how fast you are. It will show you who you are when the going gets tough.” — The Kočevsko Deer
The 25 km Deer Trail is a varied circular trail designed for runners who already have some trail-running experience and want to take the next step towards longer distances. It offers a genuine sporting challenge while remaining runnable enough for those who manage their energy wisely and maintain a steady pace.
The race starts and finishes at Lake Kočevje. After passing through Šalka vas, the route quickly enters the vast forests of Kočevsko and continues towards Somova gora, Onek, Mačkovec and Kapelica. Forest sections alternate with shorter climbs and descents, keeping the course varied throughout.
Around halfway through the race, runners face the climb to Lovski vrh, the highest point of the route. From the summit, views open up across the vast Kočevsko forests, while an additional aid station awaits just below. During the climb, the route joins the 35 km and 50 km courses.
From there, the trail heads back towards Lake Kočevje. In the final section, it merges with the 15 km, 10 km and 5 km courses before they all lead together towards the finish line and the vibrant energy of the festival venue.
For runners with some trail-running experience | Mostly through the Kočevsko forests | A varied course where rhythm and endurance matter
