K42 Canarias Anaga Marathon

The K42 Canarias Anaga Marathon will hold its 2026 edition between 4 and 6 December in Tenerife. Organised by Gesport Canarias and Patagonia Eventos SRL with the support of the Town Council of San Cristóbal de La Laguna, it is a mountain race that runs through the north-west of the Anaga massif, an area declared a Biosphere Reserve. The routes combine mountain trails, forest tracks and some urban sections, with a shared finish in the centre of La Laguna. The programme brings together the K42 events, also in the Parejas format, K30, K21, K12 and KVertical. The main distance is 42 km and 2,365 metres elevation gain; the rest of the routes range from 5 to 29 km. The vertical opens the event on Friday, K30 and K12 are contested on Saturday, and K42 and K21 close the event on Sunday. The organisers publish the official GPX tracks for each route and keep entries open until 30 November or until the places are filled.
