🏊 Got a public pool regular in mind?

Three tiers from complete beginner to confident swimmer, all in short, busy-pool-friendly sessions. Great for yourself, or to share with someone you know who swims.

Most SwimOpti profiles use three ability tiers. Pick the one that honestly describes where you are right now — not where you want to be. It is always better to start one level lower and progress than to start too high and struggle.

Beginner Building Foundations
You can: Complete 50–100m without stopping, even if slowly. You feel comfortable in the water but your technique is unpolished and you run out of breath sooner than you'd like.
Sessions are 25–35 minutes. One technique cue per session. No complex intervals.
Intermediate Growing Confidence
You can: Complete 200–300m continuously without stopping. You have a recognisable stroke and consistent breathing, but technique breaks down when you push harder or swim further.
Sessions are 35–45 minutes. Drill sets followed by longer swims. Some effort variation.
Confident Ready to Push
You can: Complete 400m or more without stopping. You swim regularly, have solid technique, and are ready for structured intervals, effort variation, and time trials.
Sessions are 45–55 minutes. Named drills, descend sets, SPL tracking, benchmark time trials.

Tier names by profile

🟢 Breaststroke Beginner  Intermediate  Confident Swimmer
🔵 Front Crawl Beginner  Intermediate  Confident Swimmer
🏊 All Round Beginner  Intermediate  Advanced
🌊 Open Water Beginner  Intermediate  Advanced
🟡 Backstroke Beginner  Intermediate  Confident Swimmer
💡 When in doubt, go one level lower. A beginner plan done well will still make you faster. An intermediate plan done poorly won't. You can always re-generate at a higher level once the current plan feels comfortable.
