21K Ciudad de Huelva

The 21K Ciudad de Huelva is a 21 km road race held in Huelva, Spain. It begins at Plaza de la Constitución and typically takes place in November. This half marathon is certified on the RFEA national calendar. The City Council of Huelva sponsors the event, which is organized by Runner Sport Huelva SL in conjunction with Club Maratón Huelva Puerta del Descubrimiento. The course winds through numerous city neighborhoods and features minimal total uphill elevation, presenting a direct urban route rather than a challenging mountain course. This is the third edition of the event. It is also part of the Diputación de Huelva long-distance running circuit. A 5K race has been introduced to complement the half marathon, offering a shorter distance option alongside the main 21K.
