International Olympic Committee President Thomas Bach said the organization is still reviewing multiple proposals concerning the possibility of extreme heat during the 2020 Summer Games in Tokyo.
Speaking during the IOC Executive Board Meeting on Saturday in Tokyo, Bach said in addition to concerns already raised about the marathon and race walk, there are also proposals about altering the start times of the BMX and rugby competitions.
The IOC president said the international federations of those sports will review their options and have discussions with the athletes' commissions before making a decision and ultimately a recommendation to the IOC's executive board.
