• Cool-down: 200m easy swim
6. Threshold Pyramid
Purpose: Improve pacing and endurance over increasing distances.
• Warm-up: 300m swim + 200m drills
• Main Set: 100m – 200m – 300m – 400m – 300m – 200m – 100m, all at threshold pace (20 seconds rest)
• Cool-down: 200m easy swim
7. Time Trial Threshold Set
Purpose: Simulate race efforts and build confidence at threshold pace.
• Warm-up: 400m swim + 4 x 50m drills
• Main Set: 1000m swim at threshold pace (race effort)
• Cool-down: 200m easy swim
8. Negative Split Threshold
Purpose: Improve your ability to hold or increase your pace under fatigue.
• Warm-up: 300m swim + 200m drills
• Main Set: 2 x 400m, negative split (swim the second half faster than the first) at threshold pace (30 seconds rest)
• Cool-down: 200m easy swim
9. Swim/Run Threshold Intervals
Purpose: Mimic race day conditions by combining swimming and running.
• Warm-up: 200m swim + 4 x 50m drills
• Main Set: 5 x (200m swim at threshold pace + 400m run at a moderate pace) with minimal rest between sets
• Cool-down: 200m easy swim
10. Threshold Pull Set
Purpose: Focus on upper body strength and endurance.
• Warm-up: 300m swim + 200m drills
• Main Set: 6 x 100m using a pull buoy, swimming at threshold pace (20 seconds rest)
• Cool-down: 200m easy swim
Final Tips for Sprint Triathlon Threshold Swimming:
• Ensure you’re swimming at the correct threshold pace—too fast can lead to fatigue, too slow won’t challenge your aerobic system enough.
• Focus on maintaining good form, especially as you get fatigued.
• Incorporate some pull sets into your training to build upper body strength.
• These workouts should be done once or twice a week to improve your threshold pace and prepare for race day.
