第12回 ランタメトライアル(#ラントラ) 2026

The 12th Rantame Trial, also known as #Rantora, is a road running race held in the Nishinakajima District of Yodogawa Riverside Park in Nagano, Japan. This edition is set for a Sunday in late July, with registration closing a few days before the event. The available information indicates a standard riverside park road race in Japan's Chubu region, not a major marathon. The name "Rantame" implies a relaxed, trial-style event, and the hashtag #Rantora provides a concise identifier for runners to use when discussing or tracking the race.
