Participants can track their progress every 5 kilometers thanks to real-time measurement points along the course. Post-race, runners are treated to on-site stretching sessions led by former Japanese national team members.
The event also includes well-placed aid stations approximately every 2.5 kilometers and a comprehensive post-finish area for recovery drinks and snacks. To top it off, all participants receive an entry ticket to Showa Memorial Park, allowing you to explore the park's vast grounds and enjoy its recreational facilities after crossing the finish line.
