K42 Anaga Maratón 2026

The K42 Anaga Marathon is a trail-running event held in San Cristóbal de La Laguna on Tenerife, Canary Islands, Spain. Taking place in early December, it offers participants multiple ways to engage with the Anaga trails: the primary 42 km marathon, alongside 30 km, 21 km, and approximately 12 km trail runs. A vertical race is also included, meaning the weekend features a variety of mountain-running formats beyond a single marathon start. The event caters to various abilities, from those targeting the K42 distance to individuals opting for the 5 km or around 12 km non-competitive trail runs. Classifications and results are available, allowing finishers to review outcomes even for categories designated as non-competitive. In essence, this is a trail series on Tenerife, focused around La Laguna, offering distances from short excursions to a full trail marathon, plus a distinct uphill vertical race.
