Cross Triathlons

The cross triathlon follows the structure of the classic triathlon, but changes the scenery completely. Here, swimming takes place in a lake or in the sea rather than in a pool, the road bike gives way to mountain biking on technical trails, and running becomes a true trail run, roots and rocks included 🌿. The principle stays the same: link the three disciplines without any downtime, but each transition calls for a different kind of adaptation, closer to managing a nature course than racing against the clock on asphalt. The technicality of the bike leg often changes the outcome of the race: a pure time-trialist can lose precious minutes on a technical singletrack, while an experienced mountain biker can make up for a swim deficit.

Formats vary a lot from one event to another, from XS designed to discover the discipline all the way up to M or L for regulars seeking distance and elevation gain. This flexibility makes cross triathlon a fairly gentle gateway into off-road multisport: you don't need the time of a seasoned triathlete to line up; the key is to work with the terrain rather than chase pure performance. The discipline attracts both classic triathletes looking for a change and trail runners or mountain bikers curious to add another string to their bow. Season-wise, most of the calendar is concentrated between July and September, when lakes are warm enough and trails are nice and dry.

In France, the O'xyrace Val-Revermont, in the Ain, has participants swim in the Lac de la Grange du Pin before sending them onto the trails of the Revermont, the first foothills of the Jura massif: the event has even hosted the discipline’s French championship. Further south, the Défi Charcot Côte Vermeille, in Port-Vendres, combines a swim in the Mediterranean, mountain biking and trail running on the ridges of the Côte Vermeille: a race that also supports a cause, as it helps raise awareness of ALS disease and support research 🎗.

Next stop: Italy, in Trentino, for the Triathlon di Lavarone Cross e Sprint. This region is far from insignificant for the discipline, since Molveno, in that same Trentino, hosted the Xterra world championship until 2021, the global benchmark of the genre since its creation in Hawaii in 1996. Spaniard Rubén Ruzafa, multiple-time world champion in the discipline, also raced some of his finest events on these Alpine terrains 🏔. Further north, in Poland, the Cross Triathlon Szczytno plunges competitors into the lakes of Masuria, a region nicknamed the land of a thousand lakes, for a Scandinavian-style take on the genre 🇵🇱.

To find your next target race, the cross triathlon calendar brings together events held mainly in summer, in France and elsewhere in Europe. If the idea of linking three disciplines appeals to you without necessarily going through MTB, take a look at trail running or swimrun, two formats that share the same taste for raw nature. Spot a cross triathlon race right now thanks to the nature theme, very common in this format, or explore the full triathlon calendar to compare it with road versions. All that’s left is to choose your playground and book your bib for your next nature outing 🎽.
