Tenerife Blue Trail by UTMB 110K is a point-to-point UTMB World Series Major crossing Tenerife island from south to north — Playa de los Cristianos at sea level to Puerto de la Cruz — passing over Mount Teide at 3,350m altitude. The 2026 edition started at 23:00 on Friday March 20. The course covers 110km with 6,250m of gain (56.8 m/km) through five biomes: beach/lava fields, Canary pine forest, volcanic plateau, the 'sea of clouds' trade-wind atmospheric layer, and laurel forest.
The average uphill gradient of 13.3% and downhill of −14.1% are both estimated in the top 10% of European trail races for sustained gradient steepness. Runners experience a 25°C temperature swing: 18–24°C at the night start to −5°C at Teide to 20°C at the coast. Entry is €1.73/km (€190 standard) and all distances are sold out. Tenerife South Airport (TFS) is 18 minutes from Los Cristianos. With 6 ITRA points and UTMB 100M category, TBT 110K suits elite and experienced mountain runners pursuing UTMB qualification on a world-class volcanic island course. Race was possibly moved due to weather.

One of Europe's most demanding volcanic island ultras. Average uphill gradient 13.33% estimated top ~10% DTR database; biggest descent drops 1,650m over 17.43km. High-altitude section (59–72km, 3,000–3,350m) slows most runners dramatically. The 25°C temperature swing — ~18°C beach start to −5°C Teide to ~20°C finish — demands careful kit management across the 27-hour window.
Yes — all three distances (110K, 73K, 47K) confirmed sold out. Registration opens in June via UTMB platform; UTMB Index holders get priority access from June 25, general from June 27.
