Route & information

10 km Trail Race of Santorini Experience

Location: Oia - Desalination Plant

The 10 km trail race starts with a slight downhill for approximately 250 meters on a wide dirt road, then follows a steep uphill path of 1,250 meters with an average gradient of 12%. The path then narrows and the terrain changes with many stones, requiring increased attention. The gradient is downhill until the 2.5 km mark where the 1st feeding station will be. Afterwards, the route goes onto asphalt for about 660 meters with a moderate uphill gradient, before re-entering a path whose ground is soft and somewhat loose earth, so a little caution is needed as it is relatively slippery, with a very steep gradient for approximately 700 meters with breathtaking views.
The intense uphill ends at the 3.8 km mark at the chapel of Profitis Ilias, followed by a concrete downhill road until the 4.5 km mark (2nd feeding station) and then approximately 500 meters remain until the turning point (Colored balloon and human marker). The return route is the same except for the point after the 6th km where, before the chapel of Profitis Ilias, we take the paved path (also requiring considerable attention) which is on the right until we reach the asphalt again at the 7th km and after about 600 meters we re-enter the path for the return where we encounter the maximum gradient just before the 8.5 km mark, which approaches 40% (!) for 100 meters. The last 1.5 km of the route are downhill.
