What is the Swim Css Calculator & How does it work?

Critical Swim Speed (CSS) is the fastest speed you can swim for an extended period without fatiguing. It’s a crucial metric for endurance swimmers as it helps in setting realistic training goals and race strategies.

The CSS is typically determined through various tests, such as the 20-minute test or the 10 x 500-yard test. These tests help coaches and athletes understand the athlete’s sustainable pace and adjust their training accordingly.

CSS = \frac{D}{T}
D = Distance swum (in meters)
T = Time taken to swim the distance (in minutes)
