K3-run is an 11.2 km mixed race in Krčmaň, a village in the Olomouc region of the Czech Republic. The name translates to “run over three peaks,” describing the route's objective: a short local race with sufficient climbing to distinguish it from a flat road run. The elevation gain is reported between 210 and 350 meters, indicating a rolling course rather than a strenuous mountain ascent. The first race category commences in the afternoon, and TJ Sokol Krčmaň organizes the event.
The course crosses the three nearby high points: Větřák, Chlum, and Borek. The majority of the route follows paved or firm paths, interspersed with some grass sections, positioning it between a road race and a light trail run. Registration takes place at Sport bar Krčmaň, adjacent to the municipal office, with walkers scheduled before the running categories. The race is also known by its Czech name, Krčmaňský běh přes tři vrcholy, underscoring its local character as a village event centered on the three hills just outside Krčmaň.
