The Tenerife Bluetrail by UTMB is one of the most varied mountain races, thanks to the diverse landscapes it runs and its technical demands. After 13 editions, it has been crowned one of Europe's best mountain races and has become iconic for many athletes. Few other events give runners the chance to start from the coast, run between rock formations and volcanic peaks, climb among the jagged rocks of lava flows, take a break while contemplating the island in its entirety from the 3,555-metre summit of Teide and then descend steeply through pine and laurel forests to winding tracks by the sea on the north coast of the island. During the race, you’ll be able to observe the 'sea of clouds,' an impressive natural phenomenon created by the trade winds, which from the summit, looks like a calm sea formed by fluffy clouds. But the Tenerife race is not just designed for titans. As well as the 110k, 73k, 47k (together with the 47k Relay version), and the 24k, which make up the UTMB World Series, all types of amateur and professional athletes of different ages and physical conditions can also take part. There are also two exclusive categories for people with some functional diversity, who can also enjoy the experience of taking part in a unique sporting event. The Tenerife Bluetrail is called ‘magical’ because of all these reasons.
