Held along the Yodogawa riverbanks in the Hirakata area of Osaka, the Hirakata Ecomarathon returns on 14 September 2025 with chip-timed race options for the Half Marathon, 10K, and 5K, welcoming club runners, families, and visiting athletes. The flat, fast riverside courses are typically out-and-back or single-loop formats that suit PB attempts and beginner-friendly pacing. Organizers emphasize eco-friendly practices—encouraging public transport, minimal on-site waste, and a mandatory pre-race briefing—and provide practical logistics such as packet pickup windows, clear course marking, aid stations, and easy access from nearby train stations. The event appears on the Japan Ecomarathon calendar and in international race directories, making it a convenient choice for local and visiting runners.
