About This Race
The 73K represents the technical stepping stone between the 47K and flagship 110K distances, demanding sustained navigation through Teide's volcanic terrain while stopping short of the summit's most extreme altitude challenges. This distance typically attracts experienced trail runners seeking to test their skills on the island's diverse geology—from coastal sections through pine forests to high-altitude volcanic landscapes—without committing to the full summit ascent. Runners face significant elevation gain across varied terrain that requires both technical proficiency and strategic pacing through multiple climate zones, making it an ideal proving ground for those building toward longer mountain ultras.
Practical Info
March temperatures typically range from mild coastal conditions to cold mountain conditions at elevation, with possible cloud cover and trade wind effects.
