Mount Fitz Roy hosts Ultra Fitz Roy from 15 October

Ultra Fitz Roy, a trail-running event at Mount Fitz Roy (Cerro Chaltén), is scheduled for 15 to 17 October 2026 around El Chaltén in Argentina. The programme combines races through the mountain landscape with in-person accreditation on 15 and 16 October.

Ultra Fitz Roy brings five race distances to El Chaltén

The organiser lists the event dates as 15, 16 and 17 October 2026, while the race regulations specify competition days of 16 and 17 October. The programme offers 10K, 21K, 42K, 70K and 100K distances, placing the event across several levels of trail running rather than around a single course length.

The official Ultra Fitz Roy programme describes the setting as the mountain environment around El Chaltén and refers to marked paths, local wildlife and the surrounding natural area. Its environmental rules prohibit leaving the marked trails, while runners who leave waste on the course can be disqualified.

Mount Fitz Roy rises above a protected Andean landscape

Mount Fitz Roy stands in the northern area of Los Glaciares National Park, whose landscape combines granite peaks, glaciers, lakes and subantarctic forests. The park lies in south-western Santa Cruz Province and covers 600,000 hectares as a national park and national reserve, according to UNESCO's park profile.

UNESCO records the peak at 3,375 metres above sea level and identifies it as Cerro Chaltén, a name derived from the Aonikenk word for smoking mountain. That height explains the close relationship between the October race and the protected terrain: the event's routes use a landscape shaped by high granite summits and glacial processes, while its rules require runners to remain on designated paths.

The Argentine government describes El Chaltén as a valley within Los Glaciares National Park where the Fitz Roy and de las Vueltas rivers meet. It identifies the mountain as a 3,405-metre landmark, although the UNESCO property profile records the summit at 3,375 metres.

Race accreditation comes before the October starts

The practical schedule begins before the main competition. The organiser's regulations place personal accreditation in El Chaltén on 15 and 16 October 2026, followed by race starts across 16 and 17 October. Start times and course arrangements may be adjusted by the organiser for safety reasons, so the published race regulations remain the relevant operational reference.
