We miss events! The challenge. The camaraderie. The fun.

Until we are able to safely host large in-person events, we wanted to give USMS members a chance to rev their engines and race with swimmers all across the country.

The 2021 TYR Last One Fast One virtual event offers an opportunity to race in your favorite pool and open water events on the Swim.com app. Times can be submitted manually or via a smartwatch.

See where you stack up in your favorite event or get out of your comfort zone and try something new. The choice is yours!

Still not convinced? $5 from every entry benefits USMS Adult Learn-to-Swim grants supported by the USA Swimming Foundation. By entering, you are helping someone else learn the sport we all love.

Best of all, you can race as many times as you’d like during the event. All swims will be recorded in your Swim.com feed, but only your fastest will appear on the leaderboard. Make your last one, the fastest!


Friday, April 16 – Sunday, May 2, 2021. This is the timeframe USMS Spring Nationals is typically held (now postponed to July 21-25)


Any 25-yard pool or open water venue. All standard 25-yard pool individual events and open water distances from 1 mile to 25K. No relays will be offered. 
*If you do not have access to a 25-yard pool, you can use a time conversion tool (i.e.
SwimSwamSwimming World) to convert your time to 25-yards and manually input them.


All USMS members are encouraged to participate. Check out the event roster. Not a member? You can fix that here.

  • How Do I Compete? 

    You must link your My USMS account with your Swim.com account in order to compete.

    You can choose to compete in as many of the events as you’d like on the Swim.com app. There is no limit as long as you swim them between April 16 – May 2 and log the results by May 4. Swims can be uploaded manually or using a compatible device (Garmin, Apple Watch, etc.). Don’t worry if you don’t have a smartwatch! Manual results can be timed by a coach or friend with a stopwatch, regular watch, pace clock, or anything else that displays times. :)

    Swim.com has made several upgrades since the 2020 Toyota USMS Virtual Championships. Most notably, times will be recorded to the hundredth of a second.

    USMS starts and strokes rules apply, but we will be using the honor system. Swim fast. Swim fair. USMS reserves the right to remove any clearly incorrect results. 

    Results and Rankings

    Results and rankings are displayed in the Swim.com app leaderboards which are filterable by gender, age group, and manual or device entry. You can also view results on a desktop here.

    This is not a customary USMS national championship. Results will not be eligible for USMS records or used to determine Top 10, All-American, or All-Star status.   


    TONS of prizes will be offered from TYR! Swimmers must have paid the entry fee to be eligible for the random drawings.
