Swim Speed and Endurance Plan

A 10-week structured plan for experienced swimmers chasing faster times and longer distances. Intervals, drills, and threshold work.

Advanced

Overview

You can already swim well. Now it's time to swim faster and further. This 10-week plan is built around structured sets — intervals, threshold work, and targeted drills — to sharpen your speed and build serious endurance.

By the end, you'll be ready to race anything from a 1,500m pool event to a 3km+ open water swim with confidence.

Golden Rule: Speed comes from efficiency, not effort. The fastest swimmers in the pool are usually the smoothest, not the ones thrashing the hardest.

What You'll Need

  • Pull buoy — isolates your upper body for targeted arm work
  • Hand paddles — builds power in your catch and pull phase
  • Fins (short blade) — improves kick technique and body position
  • Tempo trainer or pace clock — essential for hitting interval targets
  • Training log — track your sets, times, and stroke counts weekly

Understanding the Session Types

Session Type Abbreviation What It Means Effort Level
Endurance EN Long, steady-paced swimming to build aerobic base RPE (Rate of Perceived Exertion, 1–10 effort scale) 5–6 / conversational
Threshold TH Sustained hard effort — your "comfortably uncomfortable" pace RPE 7–8 / can speak in short phrases
Speed SP Short, fast repetitions with full recovery RPE 9–10 / maximum effort
Drill DR Technique-focused sets with specific focus points RPE 3–4 / slow and deliberate
Recovery REC Very easy swimming to flush out fatigue RPE 3–4 / effortless
