Elevation Profile
With 129m of total climbing, this is a gently undulating course. The elevation changes are manageable for most runners and shouldn't greatly affect your pacing.
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.

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.
