Seven Bridges Marathon 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.
