Planning a Training Camp? Top Altitude Training Locations for Triathletes
Four altitude destinations where the sport’s best train and many age-group athletes aspire to go.
Altitude training remains one of the most established, research-backed strategies for improving endurance performance in triathlon. While individual responses to altitude exposure vary and its benefits are not uniform across all athletes, it continues to play a central role in the preparation of many of the world’s top professionals.
Increasingly, elite age-group triathletes are also incorporating altitude training into their performance plans, whether to pursue marginal gains, prepare for championship racing, or replicate the environments used by the sport’s best. At the same time, these destinations appeal for reasons that extend beyond physiology alone. Many high-altitude hubs double as world-class training camp venues and aspirational travel experiences, popularized through social media and behind-the-scenes access to professional athletes’ training lives.
Here is a closer look at four of the most popular altitude training destinations in triathlon, each offering a distinct combination of elevation, infrastructure, and training culture.
Font-Romeu, France (1,850m)
Font-Romeu has become one of the most frequently cited altitude bases in triathlon, with the Norwegian stars, Olympic champion Cassandre Beaugrand, and many other top professionals training here.
It is known for the completeness and intentionality of its training ecosystem. The town sits at a live-high elevation that supports hematological adaptation, while offering rapid access to lower-altitude terrain for high-intensity sessions.
At the centre of the hub is the CNEA (Centre National d’Entraînement en Altitude), which provides a rare concentration of resources in one location: an Olympic-standard pool, outdoor track, extensive forest trail network, strength and conditioning facilities, and on-site physiological testing and performance laboratories.

St. Moritz, Switzerland (1,800m)
St. Moritz is another one of triathlon’s most established altitude training bases and is perhaps best known as a long-time training venue for GOAT Daniela Ryf. The Swiss alpine hub has also featured prominently in the preparations of Patrick Lange and Laura Philipp, along with other leading long-course athletes drawn to its combination of elevation, infrastructure, and deeply ingrained endurance-sport culture.

The town offers a pristine alpine environment with access to open-water lakes, extensive running trails, and a 50m pool at the OVAVERVA Pool, Spa and Sports Centre. These assets are further supported by the St. Moritz Altitude Training and Competition Centre, which provides services specifically designed to support performance across disciplines.

Boulder, Colorado (1,650m)
Boulder is known globally not just as a training destination, but as a place many of the world’s top triathletes live year-round and call home. Athletes who have based their training in Boulder include Taylor Knibb, Chelsea Sodaro, Holly Lawrence, Mirinda Carfrae and Tim O’Donnell, and many others.

Situated at a moderately high elevation, Boulder allows athletes to live high enough to benefit from chronic altitude exposure while remaining low enough to largely preserve training intensity. Proximity to the nearby mountain ranges also enables strategic excursions to higher elevations when desired.
Boulder’s depth of infrastructure further reinforces its status as a triathlon hub. Beyond its extensive network of pools, trails, and iconic cycling routes, the city offers a dense concentration of elite training groups alongside experienced coaches with deep sport-specific expertise.

Sierra Nevada, Spain (2,320m)
Sierra Nevada is one of the highest major altitude training centres regularly used in triathlon and endurance sport. The venue is another frequent base for the Norwegians.

At 2,320m, Sierra Nevada represents a true live-high, train-high environment, delivering a strong physiological stimulus while demanding careful management of intensity and recovery. Many athletes pair extended stays at altitude with regular descents to nearby Granada to access higher-quality sessions when needed.
The hub of the complex is the CAR Sierra Nevada (Centro de Alto Rendimiento), which offers a comprehensive suite of facilities in one location, including a 50m pool, indoor and outdoor tracks, strength and conditioning spaces, and advanced sports-science and physiological testing laboratories.
This concludes our overview of some of the world’s top altitude training locations – and, hopefully, offers inspiration to experience one firsthand.
