The design depicts, on the left side, a marathon runner and, on the right side, a detail of St Elizabeth’s Cathedral, one of the architectural landmarks of Košice. Inscribed across the lower part of the design are the name of the issuing country ‘SLOVENSKO’ and, below it, the marathon’s inaugural year ‘1924’ and the coin’s year of issuance ‘2024’. The inscription ‘KOŠICKÝ MARATÓN’ runs along the edge of the upper half of the design. Next to the lower left edge is the mint mark of the Kremnica Mint (Mincovňa Kremnica), consisting of the letters ‘MK’ placed between two dies. To the right of it are the stylised initials ‘LR’, referring to the national side’s designer Roman Lugár. The coin’s outer ring bears the 12 stars of the European flag.
