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 inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
