Tokyo Marathon 2026 sets up as one of the most competitive fields of the season (90/100). Our model sees a razor-thin margin between Ruth Chepngetich 🇰🇪 (10.8%) and Benson Kipruto 🇰🇪 (10.6%). This race could come down to the final kilometers and tactical execution.
The primary battle is between Ruth Chepngetich and Benson Kipruto, separated by just 0.2 percentage points. Kenya 🇰🇪 has 2 athletes in the top 3, adding tactical depth to their campaign. Tamirat Tola 🇪🇹 at 6.9% is the dark horse — capable of disrupting if the leaders neutralize each other.
Cool conditions (8°C / 46°F) are favorable for fast times. Cool skies should allow athletes to push the pace early. Watch for Light 6 km/h impacting the exposed sections of the course.
Too close to call between Ruth Chepngetich and Benson Kipruto. Our slight edge goes to Ruth Chepngetich based on recent form trajectory, but this is a coin-flip race.
