Based on historical weather data for July, the expected race day conditions are as follows. Hot conditions are expected, with temperatures between 15°C and 30°C. Heat is one of the biggest performance factors in distance running - for every degree above 15°C, finish times can slow by roughly 1-2%. Extra hydration and a conservative start are strongly recommended. There is a low chance of rain (2%), so dry conditions are likely.
Faethon Sky Race is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are usually slower than the road equivalent - often by 10-20% - because of uneven footing, technical sections, and frequently steeper gradients, though a smooth, non-technical or downhill trail can run faster than that suggests. Trail-specific shoes with good grip are recommended.
