1500m Swim Workout for Beginners

April 8, 2026

1500m is a meaningful distance. It’s the Olympic open water distance, the standard triathlon swim leg, and a solid workout for anyone building their swimming foundation. Here’s a beginner-friendly way to swim it.

Who This Is For

This workout is designed for swimmers who can:

  • Swim 100m without stopping
  • Comfortably do a few lengths of freestyle
  • Are building toward longer swims

If you’re still working on swimming continuous 100m, start shorter and build up.

The Workout

Total: 1,500m

Warm-Up — 300m

  • 200m easy freestyle, focus on relaxed breathing
  • 4×25m, rest :20 between each (these are short — rest fully, go easy)

Skill Set — 200m

  • 4×50m as 25m kick + 25m swim, :20 rest
  • This wakes up your legs and lets you practice your kick without exhausting yourself

Main Set — 800m

  • 8×100m on 2:30 (take full rest — this is meant to feel manageable)
  • Aim for even pace. If your first 100m is 2:00 and your last is 2:30, you went out too hard.

Cool-Down — 200m

  • 200m easy, backstroke or breaststroke if possible

Pacing Tips for Beginners

The most common beginner mistake: sprinting the first 50m, then gasping through the rest.

For each 100m in the main set, consciously start slower than you think you need to. If your comfortable 100m pace is 2:10, start at 2:15. You’ll have gas left at the end.

Signs you’re at the right pace:

  • You can breathe consistently (not gasping)
  • You could sustain this for another 50m if needed
  • You don’t feel urgent relief when you hit the wall

How to Progress

Once this workout feels manageable:

  1. Reduce rest on the main set from 2:30 to 2:15 intervals
  2. Add a rep to the main set (go from 8×100m to 10×100m)
  3. Try building the cool-down to 400m

Build one variable at a time. Don’t reduce rest AND add reps in the same session.

Logging Your Progress

Record your average 100m time from the main set after each session. Even if it’s 2:20, log it. Over 6–8 weeks of consistent training, you’ll see that number drop. That’s concrete proof that your training is working.
