Course elevation profile, 8× vertical exaggeration Elevation along the course from km 0 to km 122. The trace runs between 410 and 2131 metres, a range of 1721 metres, drawn at 8 times vertical exaggeration so the shape is legible. Smoothed over 1 km before this profile was derived. An unsmoothed urban surface carries the buildings and would assert a climb that is not there. The dashed stretches are bridge decks: Cesta svobode, km 0.3 to 0.4; Bodeški most, km 6.3 to 6.4; Veslaška promenada, km 42.9 to 42.9; (unnamed span), km 54.1 to 54.2. A bare-earth model reads the ground or the water beneath a bridge, not the deck the runner is on, so those runs are interpolated between the ground either side rather than measured, and they under-report the real climb across a span.

The race is the queen stage of the Julian Alps Trail Run, with 32 hours allowed. After the start in the old town of Radovljica the route climbs to the Jelovica and Babji zob, descends to Lake Bled, and turns towards Žirovnica for the climb of Stol.

From Stol the route crosses the ridge to Golica and Klek, drops to Mojstrana, climbs again from Gozd Martuljek to Srednji vrh, and finishes with a downhill into Kranjska Gora.
