This will be my first Nationals meet, and two of the events I'd like to swim are back-to-back. How much rest is there generally between consecutive events at Nats (i.e., the 200 IM and the 100 free)? I'm F40-44 and would be swimming the 100 free qualified and am close in the 200 IM, if that makes a difference in heats. Thanks!
