Overview

• The change covers all road events on the first three days, with the 35km race walks and the marathons now set for 7:30 a.m., while in-stadium schedules remain unchanged.
• Organisers are adding 185 water points on the marathon route, installing radiative-cooling tents near venues, and equipping staff and volunteers with core-temperature monitoring devices.
• Japan recorded its hottest summer since 1898 with average temperatures 2.36°C above the norm, and Tokyo logged more than 3,300 heat-stroke hospitalisations last month.
• Road events will stay in Tokyo rather than relocating as in the 2021 Olympics, though officials say further timetable adjustments are possible if conditions warrant.
• World Athletics leaders, including Sebastian Coe, describe heat risks as persistent effects of climate change and say the sport will make scheduling decisions to prioritise athlete welfare.
