For your November variant (3 November 2025), the Yodogawa Ecomarathon would take place along the flat, scenic Yodogawa riverbanks in Osaka with chip-timed Half Marathon, 10K and family 5K options—courses designed to be fast, beginner-friendly, and low-impact. Race logistics typically include mandatory pre-race course briefings, clear course marking, aid stations, on-site packet pickup windows, and an emphasis on eco-friendly transport and “take your trash home” policies. The event usually starts late morning (around 11:00 for family/shorter distances) and attracts local clubs, families, and international runners seeking a relaxed, well-run urban riverside race. Important: the organizer’s published calendar and major race directories list the next confirmed Yodogawa Ecomarathon in mid-September 2025 — please confirm the November date with the official event page before distributing.
