Get your year off to a fresh start with the USMS Fitness Series and the Winter Fitness Challenge, a 30-minute swim that takes place between Jan. 1 - 31.

Whether you're just getting into swimming, starting back into it after a break from the pool, pushing to see how fast you can go, or just wanting to donate to USMS Adult Learn-to-Swim grants supported by the USA Swimming Foundation. The Winter Fitness Challenge is the perfect event for you to leap into the new year. The Winter Fitness Challenge can be done in any manner desired: straight through, as a member of a relay, or even with fins. 

The WFC overlaps with the 2023 USMS 1-Hour Virtual Championship so all swimmers on your club can participate. The choice is yours: 60-minute competition or 30-minute fitness challenge. Everyone earns their post-swim donut!

If you need help preparing for your swim, we have six-week training plans for all types of swimmers.


The USMS+ membership combines the great benefits and experience of a standard USMS membership with additional access and benefits at a surprisingly low price - including entry into the 2023 Fitness Series! As a USMS+ member, you will need to register for the Fitness Series, but you will not be charged the registration fee.  

Bundle Registration and Gold Caps

USMS members can now register for all three challenges in the Fitness Series at the same time! Not only will you receive a discount, but you will also receive a special gold cap in addition to the cap for each event. In order to take advantage of the bundle pricing, you need to sign up before Jan. 31. To access the bundle pricing, go through the standard Winter Fitness Challenge member registration and select the bundle. It's that easy!

Note: caps are latex. Please email if you do not wish to receive caps. 

Log Results on the App

  2. Find and join the challenge on the app (here is how)
  3. Complete your swim or workout
