World Athletics president Lord Sebastian Coe admits that settling on a new date for the Tokyo Olympics in 2021 will not satisfy everybody.
The 2020 Olympics, which were set for July 24-August 9 this year, were postponed until 2021 by the International Olympic Committee (IOC) this week because of the coronavirus.
On Saturday (NZ time), the IOC confirmed a decision on when the Games will take place can be expected next month, dates between April and August being suggested.
But the postponement of the Games will likely see a number of other events have to shift their schedules around to accommodate.
"All sports have made it pretty clear they have particular challenges at particular times of the year," said Coe.
"We are probably not going to reach a solution that meets with the approval of every sport.
"But there does have to be an element of flexibility and there is going to be flexibility for the next two years.
"There are clearly demands for this decision to be taken as quickly as possible - the athletes and the federations need clarity.
"Once the decision is made, we can build [the calendars] around it."
The next Athletics World Championships are scheduled to take place in Eugene, Oregon in August 2021 but Coe says the event may need to be moved to avoid clashing with the Olympics.
"At this stage, it's fair to say nothing is on the table, nothing is off the table," Coe added.
"But clearly it is an advantage in athletics not to have an Olympics and a World Championships in the same year.
"We have already had good discussions with Oregon and what I can report is Oregon are very clear that they will do whatever they can to help in our deliberations on this.
"No hard and fast decisions have been made. It may well be that one of the options is to move into 2022, but that's where our discussions are now taking place."
Meanwhile Coe expressed his support for the IOC's decision to postpone the 2020 Olympics.
"When we get through this, and we will, we will be braver and more innovative," he said. "We will be more collaborative and resilient. We will be stronger and more tolerant. We will be more global, not less.
"In sport, we have a unique opportunity not to tiptoe around things and tweak at the edges.
"We have the chance to think bigger, to rip up the blueprints and banish the 'that's the way we've always done it' mentality.
"Ironically, I believe social distancing will actually bring us closer together as a community and sport can sit right at the centre."
"No hard and fast decisions have been made. It may well be that one of the options is to move into 2022, but that's where our discussions are now taking place."
