If last year's ten-race roundup covered the 2026 season, this one is for anyone already looking past it. A surprising number of European ultra organisers publish next year's dates, and open registration, well before the current season has even finished. By the time UTMB week wraps up in Chamonix this August, several 2027 races will already have entries open, and a few will already be filling up.
This list only includes races with dates the organisers have officially confirmed. A few of the biggest names on last year's list, Spartathlon and Tor des Geants among them, had not yet published their 2027 editions at the time of writing, so they are left off rather than guessed at. What follows are seven races across five countries with real, published 2027 dates, running from late February through early August.
1. The North Face Transgrancanaria
📍Location
Gran Canaria, Spain
📅 Dates
February 22 to 28, 2027
📏 Distance
128km (Classic flagship)
Transgrancanaria opens the European ultra season while most of the continent is still deep in base training, which is exactly why it works so well as an early-year target. The Classic route crosses the island coast to coast, through pine forest, exposed volcanic ridgelines, and the kind of technical descents that reward runners who have actually done hill work over winter rather than just logged flat miles indoors.
Registration for the 2027 edition opened on 1 July 2026, with several distances historically selling out within the first weeks. For northern European athletes, a late-February race in the Canary Islands offers a genuine training-camp advantage: warm enough to escape a European winter, technical enough to be real preparation rather than a holiday jog.

2. Tenerife Bluetrail by UTMB
📍Location
Tenerife, Canary Islands, Spain
📅 Dates
April 8 to 10, 2027
📏 Distances
110km (flagship), 82km, 68km, 47km, 24km
Tenerife Bluetrail climbs from sea level toward the volcanic summit of Mount Teide, and the elevation swing is the whole story here: routes that start in coastal heat and finish in genuinely alpine, sometimes near-freezing conditions at altitude. It is a UTMB World Series event, so Running Stones earned here count toward UTMB qualification, and the longer distances have historically sold out well ahead of the race itself.
The layered distance options, from a 24km taster up to the full 110km, make Tenerife Bluetrail one of the more accessible entry points on this list for athletes who want UTMB-series terrain without committing to a 100km-plus distance on a first attempt.

3. La Sportiva Lavaredo Ultra Trail by UTMB
📍Location
Cortina d'Ampezzo, Italy (Dolomites)
📅 Dates
June 23 to 26, 2027
📏 Distances
120km (flagship), 80km, 50km, 20km, 10km
The Dolomites in June, viewed from a start line at midnight in Cortina's Piazza Roma, is one of the more atmospheric openings in European trail running.
The 120km flagship winds beneath the Tre Cime di Lavaredo through UNESCO-protected terrain, a course that takes most finishers somewhere between 18 and 30 hours and rewards runners who have specifically trained for technical rock and scree rather than smooth alpine singletrack alone.
The shorter distances, all the way down to 10km, make Lavaredo one of the more family-friendly race weekends on this list, and the 50km and 80km both qualify for UTMB Running Stones, making them useful stepping stones toward a longer target the same season.

4. Marathon du Mont-Blanc
📍Location
Chamonix, France
📅 Dates
June 24 to 27, 2027
📏 Distance
Up to 90km
Not to be confused with UTMB itself, the Marathon du Mont-Blanc is its own multi-day festival built around eight distances, from a short family race up to a genuinely demanding 90km mountain ultra, all sharing the same Chamonix base and the same jaw-dropping Mont-Blanc massif backdrop.
For athletes not yet chasing UTMB qualification points, it is one of the most complete introductions to Chamonix mountain running available, without the multi-year Running Stones build-up UTMB itself requires. The overlapping dates with Lavaredo, just one valley system away in the Dolomites, make late June a genuinely difficult weekend to choose between if both races are on your radar for the same season.

FAQs
Why plan this far ahead?
Registration for several of these races opens six to twelve months before the start line, and the longer, more sought-after distances at Transgrancanaria and Tenerife Bluetrail, have sold out ahead of the event in recent years.
Planning your 2027 season now, while most of the field is still focused on finishing 2026, is less about being obsessive and more about not losing your preferred distance to a waitlist. It also means the training block behind each of these races can be planned properly rather than compressed into a rushed few months once a late entry finally comes through.
A full off-season and base-building block, built around a known start line and a known date, is worth considerably more than the same number of training weeks squeezed in after a late scramble to find an open spot.
How should you actually decide which of these seven to target?
Distance and terrain matter more than name recognition when narrowing this list down to one or two races for your season. Transgrancanaria and Tenerife Bluetrail both suit athletes who want technical volcanic terrain without alpine altitude. Lavaredo sits squarely in classic high-alpine terrain, big climbs, technical descents, and genuine altitude exposure, while Marathon du Mont-Blanc offers a lower-commitment entry into the same Chamonix ecosystem without the UTMB qualification requirement.
How OLEUS fits into planning this far ahead
An early-confirmed race date is only useful if the training block behind it is built properly, and that starts well before race week itself. The Pre-Activity Shot, taken 30 to 60 minutes before your hardest training sessions through the months leading into any of these races, primes the same cellular energy systems, oleuropein, L-citrulline, caffeine from guarana, magnesium, and a B-vitamin complex, that will matter on the start line. What you do with the training block between now and the start line is what actually determines how the race goes.

The Pre-Activity Shot fits the 30 to 60 minute window before every hard session between now and the start line.
