Colorado Masters Swimming Association (COMSA) includes all USMS-registered clubs, workout groups, coaches and swimmers in Colorado and Wyoming.

As of October 2024, there were almost 1,400 individual members and 15 clubs (including a large regional club with 900+ members and 23 workout groups) registered with COMSA.

Club affiliations are encouraged but not required. Unattached (UC32) members have no team affiliation and cannot score team points or swim in official relays at USMS sanctioned or recognized meets.


New for 2025 - Rocky Mountain Regional Masters (RMRM) replaces Colorado Masters Swim Club (CMS). 
This club name transition was made to be more inclusive of the two states we represent, Colorado and Wyoming. As you go to renew your USMS membership, please note the Colorado Masters Swim Club (CMS) has gone away, and the new club Rocky Mountain Regional Masters (RMRM) will be the new club for many COMSA swimmers. If you were previously a member of a CMS workout group, that name will remain the same. When you go to renew, if you were previously a CMS member, your renewal information will indicate RMRM, but your workout group will remain the same as 2024. You do not have to be associated with a workout group to be a part of the RMRM club.

Members who affiliate with Rocky Mountain Regional Masters (RMRM) may also affiliate with a USMS-registered RMRM workout group. RMRM is a regional club: its members compete as their registered workout-group team (local team) when entering COMSA-sanctioned events and as their RMRM club team when competing in national championships or other events sanctioned outside of COMSA.

USMS does not recognize workout-group affiliations outside of the swimmer’s home LMSC. Swim times are always recorded in World Aquatics and USMS results databases under the swimmer’s club affiliation, not their workout-group affiliation.


 

Club & Workout Group Registration 

To register or renew a club or workout group with USMS for 2025, click on the online registration link below for instantaneous registration using a credit or debit card. 

The club / workout group registration fee for 2025 is $75. 

Individual members who join or renew with USMS for 2025 can only affiliate with and compete for a club/WG that has registered with USMS for 2025. Therefore, to avoid confusion, current USMS-registered clubs and workout groups should renew for 2025 during October 2024 before individual “early bird” USMS registration opens on November 1, 2024.
