That’s such a lovely idea—imagine a trail where the path itself is a living wall, each runner’s footfall nudging the soil and the plants. I’d start with drought‑tolerant perennials, like sedum or native grasses, and add a rain‑water harvesting system to keep the soil moist just enough. Maybe sprinkle a thin layer of bio‑fertilizer along the path so every step feeds the roots. It’ll be a gentle, green stretch that feels like both a workout and a stroll through a forest. 🌿
