Swimming Training Stress Score (sTSS) is a metric that quantifies the training load of a swimming workout by combining both intensity and duration. It's adapted from cycling's TSS methodology, using your Critical Swim Speed (CSS) as the threshold pace. A workout of 1 hour at CSS pace equals 100 sTSS.

Use the calculator above by entering your CSS pace (from a CSS test), total workout duration, and average pace during the workout. The formula is: sTSS = Duration (hours) × Intensity Factor² × 100, where Intensity Factor = CSS Pace / Average Workout Pace.

Yes, your Critical Swim Speed (CSS) is required to calculate the Intensity Factor, which is essential for sTSS calculation. CSS represents your threshold pace and should be tested every 6-8 weeks. You can find your CSS using our CSS calculator.

It depends on workout intensity: Easy workouts typically score below 50 sTSS, moderate workouts 50-100 sTSS, hard workouts 100-200 sTSS, and very hard workouts above 200 sTSS. The appropriate score depends on your training goals and current fitness level.

Weekly sTSS targets vary by level: Recreational swimmers: 150-300, Fitness swimmers/Triathletes: 300-500, Competitive Masters: 500-800, Elite/Collegiate: 800-1200+. Start conservatively and increase gradually to avoid overtraining.

The concept and formula are the same, but sTSS is adapted for swimming. Instead of using power (FTP) like cycling TSS, sTSS uses pace with CSS as the threshold. Both measure training load using Duration × Intensity Factor² × 100.

Yes, but your CSS should be stroke-specific. Most swimmers use freestyle CSS since it's the most commonly trained stroke. If you train primarily in another stroke, perform a CSS test in that stroke and use that pace for sTSS calculation.

sTSS measures a single workout's training load. CTL (Chronic Training Load) is your long-term fitness, ATL (Acute Training Load) is your recent fatigue, and TSB (Training Stress Balance) is your freshness. These metrics use sTSS values over time to track your training state. Learn more in our Training Load guide.
