USA Swimming announced tentative dates on Monday for six meets leading to next year's Olympic trials, with hopes of resuming some regional events as soon as August.
The coronavirus pandemic that forced postponement of the Tokyo Olympics to 2021 wiped out most US meets, with the US summer national championships called off on Monday with hopes for regional events by late August to help swimmers return to pools.
"These regionally focused events will limit the need for travel and promote a safer competition environment," USA Swimming said.
The 2021 US Olympic swimming trials, where such stars as five-time Olympic champion Katie Ledecky, were already announced for 13-20 June at Omaha, Nebraska, slightly earlier than had been planned this year.
The US Pro Swim Series is tentatively set to begin 5-8 November at Richmond, Virginia, followed by the US Open meet 2-5 December in Atlanta.
Pro Series meets are planned for 13-16 January at Knoxville, Tennessee; 3-6 March at San Antonio, Texas; 8-11 April at Mission Viejo, California and 12-15 May at Indianapolis.
