Because there will be several months this year without RUSA sanctioned events, for any RUSA Cup effort in progress at the time events were put on hold, you will have three years to achieve the RUSA Cup rather than two.
For example, if your first qualifying event was on 1/1/2019, you now have through 12/31/2021 to complete. If your first qualifying event was on 2/1/2020, you now have through 1/31/2022 to complete.
