Expected Race Day Weather

Based on historical weather data for May, the expected race day conditions are as follows. Moderate temperatures between 17°C and 21°C are expected. While comfortable for most runners, those targeting fast times should pay attention to hydration, as these temperatures can impact performance on race day. There is a low chance of rain (3%), so dry conditions are likely.

Surface Type: Trail

Navarino Challenge 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.
