Plan Tokyo Great Race 250km
Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.
Edition notes: The seventh edition runs November 6–8, 2026. The 244 km race started at 11:00 AM JST on Friday, November 6, at Kiba Park, and its 48-hour limit ends at 11:00 AM JST on Sunday, November 8, at the Eitai District Community Hall. Despite the 250KM in the name, the organizer’s entry page and DUV both list the course as 244 km (152 mi). A 124 km (77 mi) race over the first half started at the same time and ends at Musashi-Itsukaichi. A 120 km (75 mi) race over the second half starts at 11:00 AM JST on November 7 at Akigawabashi River Park. The entry page links no live tracking or results page. For 2025, the entry page gives November 7–9, while DUV dates the 2025 results November 8–9 (EL wave) and November 8–10 (RE wave).
