Running Track Surface Transitions: Hard Paving, Gravel, and Wooden Decks

Show a running loop in a sports park where the surface deliberately changes along its length, and frame the view at one of the transitions. Render three surfaces meeting within the frame: a smooth asphalt section with a fine texture for speed, a softer compacted decomposed granite section in a warm buff tone for lower impact, and a raised timber boardwalk section crossing a wet area on slim piles. Detail each junction as a clean flush transition with a discreet edge — a slim steel strip between asphalt and gravel, a bevelled timber threshold at the boardwalk end — so a runner's stride is never interrupted by a lip. Show a small marker post at the transition giving distance and surface type in simple pictograms. Detail the boardwalk with a fine gap between boards, a non-slip insert strip and no handrail where the drop is low. Include planting close to the path edge on the gravel section and reeds beside the boardwalk. Show morning light with a runner approaching the transition. Photorealistic, tactile, material-focused, low eye-level view along the path.
