Obala Ultra Trail is a scenic trail running event connecting the Slovenian coastline, Karst edge, and charming Istrian villages with panoramic views of the Adriatic Sea.
What this race demands
The Obala Ultra Trail requires maintaining forward progress across 108 kilometers and 4000 meters of elevation change along technical coastal and karst terrain. Athletes must manage significant cumulative fatigue over an endurance effort lasting well beyond a standard day.
Distance endurance
Covering 108 kilometers demands exceptional muscular endurance and pacing discipline to sustain forward movement over many hours.
Climbing volume
Accumulating 4000 meters of elevation gain requires specialized leg strength and efficient uphill hiking mechanics to handle sustained gradients.
Downhill durability
Traversing the rugged Karst edge and Istrian hills involves continuous descents, placing high eccentric loading demands on the quadriceps.
Given the duration of this ultra-distance event, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy availability and prevent late-race depletion.
