Entry

---

Chase a personal best on Tokyo's flat Arakawa riverside out-and-back. JAAF/World Athletics certified, 7-hour limit, first-come entry via RUNNET in early August.

Why attend here

Come for the flat, fast course along the Arakawa river in early spring, when Tokyo's air is crisp and the cherry blossoms are just starting to hint at pink. After the race, wander the old-school lanes of nearby Jujo for a bowl of steaming ramen, or soak in a local sento to ease tired legs—a quiet, rewarding way to cap off a PB attempt.

Course

An almost dead-flat out-and-back along the Arakawa river flood plain with negligible elevation change, which is why it is one of Japan's most reliable personal-best courses.
