Santorini Experience 2026: The Ultimate Autumn Sports Event Returns to the Caldera

For over a decade, the Santorini Experience has stood out as one of the most visually stunning and physically demanding sports tourism events in the world. Celebrating its 12th year, this spectacular three,day gathering is officially scheduled to return from October 16 to 18, 2026.

Co-organized by the Municipality of Thira, the local Department of Sports and Culture, and ActiveMedia Group, the event has already earned twelve accolades at the prestigious Sports Marketing Awards and Tourism Awards. Offering a seamless blend of elite athleticism, raw natural beauty, and local history, it continues to attract professional and amateur athletes from across the globe.

A Historic Premiere: The Ancient Thera Run 5K

The 2026 edition introduces an exciting addition to its traditional schedule. On Friday, October 16, 2026, at 17:30, the event kicks off in Kamari with the premiere of the Ancient Thera Run 5K.

Unlike the classic caldera paths, this brand,new trail run unfolds at the foot of the landmark Ancient Thera archaeological site. The route capitalizes on a dramatic landscape where the Aegean Sea directly meets the rugged mountain slopes, promising unique surprises for runners at every checkpoint.

The Legendary 2.4km Open Water Swim

On Saturday, October 17, 2026, at 09:30, swimmers will face one of the world’s most unique open-water courses. Competitors will board vessels provided by the Santorini Boatmen’s Association, which will transport them directly to the volcanic islet inside the caldera.

From this volcanic starting line, participants swim 1.5 miles, or 2.4 kilometers, across the deep, dark waters of the caldera, finishing at the historic Old Port of Fira. To guarantee absolute safety, lifeguard boats will accompany the swimmers, and the use of a safety buoy is mandatory. As a courtesy, the organization provides free round-trip cable car access to the Old Port for all registered swimmers upon showing their proof of entry.

Caldera Trail Running: Three Routes for Every Level

On Sunday, October 18, 2026, the focus shifts to the island’s iconic volcanic cliffs. All Sunday running races will commence from the Desalination Plant in Oia, leading runners through traditional cobblestone paths, narrow alleyways, and sharp terrain changes.

The Sunday schedule includes three distinct distances to accommodate varying levels of endurance:

• 15K Trail Run (Powered by The North Face): Starting at 08:15, this grueling course features a significant elevation gain of 834 meters. It stretches from Oia along the rim of the caldera, passing through the picturesque settlements of Imerovigli and Firostefani before looping back.

• 10K Trail Run (Powered by SIXT): Also kicking off at 08:15, this intermediate course challenges runners with a 570,meter elevation gain, following a similar scenic path along the caldera’s edge.

• 5K Trail Run “Aristides Alafouzos” (Powered by Miele): Starting later in the morning at 11:00, this shorter trail run is designed for those seeking speed and adrenaline along a condensed route starting and finishing in Oia.
