Register for National Relays Here

Fill out the form below by checking the relays that you want to participate, submitting your times, and adding your contact information. How relays are formed and assigned points are explained below. Our goal is to have multiple relays in each age group competing. So the more people that are willing to swim on relays, the more potential points we can score as team Illinois Masters.

Short Course Yards

These relays are formed based on age and time. There may be multiple relays for a given age group. If this is the case, your relay will be named by the type, age and a letter.

For example, “Women’s 200 Free 25+ IM-C.”

  • The relay type is Women’s 200 Free.
  • The age of the members of the relay are 25 or older
  • The name of the relay that will appear on the event and results sheet is IM-C.

Age groups are by increments of 10 years. Ideally, you will be placed in the oldest age group possible, but there are times when you will be asked to “swim down an age group.” This means that even though your age is 36, you may be placed on a 25+ relay because they needed another person. The competition may be stiffer, but your time may be competitive for a younger age group. In the case of an older person, there may not be enough swimmers in your age group.


Long Course Meters

For long course meters, your age is how old you are on December 31 of that year. Relay age groups are determined by the sum of the ages of the four relay members. Age groups are as follows: 72-99, 100-119, 120-159, 160-199, 200-239, 240-279, 280-319, 320-359, 360-399. As in short course yards, there may be more than one relay per age group.

For example, “Mixed 200 Free 160-199 IM-A”

  • The relay type is Mixed gender, with two males and two females each swimming 50 meters freestyle.
  • The age of the members add up to a number between 160 and 199 inclusive.
  • The name of the relay is IM-A. This will appear on the heat and result sheets.


We are no longer taking relay requests for the 2024 USMS Short Course Nationals held in Indianapolis.
