Four-time Olympic champion Matthew Pinsent believes it is "folly" for the International Olympic Committee (IOC) to insist the Tokyo Games will go ahead.
IOC chairman Thomas Bach said on Tuesday that starting on schedule on 24 July remains the organisation's goal, despite much of the sporting calendar being shut down due to the coronavirus pandemic.
"I think it's the IOC saying we must try and get through if we can, which I have a degree of sympathy with, it just runs counter to what every health authority and government is saying around the world," Pinsent told BBC Radio 4's Today programme.
"We've seen lockdowns across Europe and across Asia at different timescales but this is coming and the idea that the Olympics are going to carry on regardless I think is folly.
"On a global front we have other priorities and I think the Olympics should at the very least be saying we should postpone or indeed just cancel at this stage and we'll talk about postponement later on.
"I just don't think there's much of a choice at this stage. For much of the European countries as well Asian countries, organised sport in any meaningful way has ceased and that's from government advice.
"I don't see there's any way forward for an Olympic athlete to train effectively even as an individual but particularly in a team environment."
