Start times for Triathlon will be brought forward due to heat concerns, Tokyo 2020 and the International Olympic Committee (IOC) revealed today.
In a joint press conference dominated by the decision to move marathon and race-walk events to Sapporo amid fears over extreme heat, Tokyo 2020 President Yoshirō Mori confirmed talks around other events.
"Discussions have been taking place over the times of competition for Triathlon," he said.
"We have come to a common understanding with the IOC and International Federations to bring forward competition times.
"With regard to the Triathlon, the Men's, Women's and Mixed Relay will be moved forward by one hour.
"This will now start at between 7.30 or 8am."
The Men's and Women's Triathlon events are due to take place at the Odaiba Marine Park on July 27th and 28th, respectively.
Both competitions are currently scheduled to begin at 7.30am, so the proposed change will move that to 6.30am.
The Mixed Team Relay is set to be brought forward from 8.30am to 7.30am at the same venue on August 1st.
The Tokyo 2020 test event in August that saw Bermudaís Flora Duffy crowned Champion saw organizers reduce the distance of the Run from 10K to 5K due to extreme heat.
The swimming and cycling segments of the event were unchanged.
