Tenerife Bluetrail 2027 Guide: the 110k island crossing by UTMB

The Bluetrail 110k does not behave like a standard ultra because it is really several races stitched together. The southern start can tempt runners into pushing too early, the long climb toward Teide changes the physiology of the effort, then the northbound descent forces you to manage fatigue, night running, altitude and long downhill damage. It is not only the distance that makes the race hard. It is the way Tenerife keeps changing the type of problem you need to solve.

The second issue is logistics. You start in Los Cristianos and finish in Puerto de la Cruz, so the right accommodation plan is not the same before and after the race. High-altitude weather matters too: mild conditions by the coast, colder wind higher up, then a more humid northern atmosphere later. The runners who handle this well are often the ones who prepare clothing, lighting and transport as seriously as training.

Useful preparation for Bluetrail 110k combines long-duration endurance, strong climbing capacity, tolerance for very long descents and confident night management. It also means rehearsing the UTMB mandatory kit exactly as required: two headlamps for the 110k, active smartphone, enough water, waterproof shell and warm layers. The more automatic your pack and routines are, the less mental energy the island crossing takes away from you.

Bluetrail logistics should be treated like an open loop. The start in Los Cristianos makes Tenerife South very practical on the way in, but the finish in Puerto de la Cruz changes the equation afterwards. If you are not using a car, you need to decide early whether you will stay south before the race and north after it, or whether official transport options really fit your plan.

The Tenerife Bluetrail by UTMB site should remain the reference for mandatory kit, authorised assistance points, drop bags and final timings. TrailCompanion is especially useful here because it turns a race that could feel messy into a clear sequence: flight, pre-start accommodation, assistance points, layering system, lighting, fueling and return plan. This is exactly the kind of ultra where logistics can save a huge amount of mental load.

Tenerife South airport is the most practical gateway if you want quick access to Los Cristianos before the race. Tenerife North becomes more logical if you leave from Puerto de la Cruz or Santa Cruz afterwards.

Without a car, the north-south return question needs to be solved seriously. With a car, the key issue becomes vehicle placement between the start and the finish or using official shuttles if they match your race plan.

Sleeping in Los Cristianos or very close to it makes the 110k start materially simpler. It is the cleanest choice if you want zero unnecessary stress before the gun.

After the race, Puerto de la Cruz or Santa Cruz make more sense for recovery. On a point-to-point course like this, booking a finish-side hotel is often smarter than trying to force everything into one single base.

Tenerife Bluetrail 110k is a true island crossing, not just a longer ultra. If you prepare the mandatory kit, the south-north logistics and the layering system carefully, Tenerife becomes a huge but readable project instead of a long improvisation.
