This map is a reference for camera locations; the official route map takes precedence. The route mainly follows the Dongshan River left-bank bike path and nearby roads (the bike path itself has no public cameras). The indicative line was planned along real roads with OSRM, not the actual bike-path alignment, so it is less reliable than other races. The full-marathon total is slightly above the official 42.195K, likely because road distance differs from the bike path.
