4-Week Base Plan Open Water Advanced (Swimming Coach) is a 4-week swimming plan. This article combines the actual plan description with a example week from the stored workout entries.
What this plan is built for
This plan is suitable for re-entering open water training. The focus is on learning open water techniques, proper orientation, rounding buoys, and flexible breathing on both sides. Compared to the beginner plan, the volumes are already significantly higher.
Training Zones Heart Rate Zones Duration Example Intensity
Recovery (Recom) > 120 5 – 60 min 200m easy 3 – 4 RPE*
Training logic and load
The emphasis is durable base fitness, clean technique, and a rhythm you can repeat for several weeks. The important part is not upgrading easy days into hidden hard days. The workout data shows which sessions are structured and which ones are intentionally simple.
The plan contains 12 scheduled entries across 4 weeks. The sequence matters as much as the total hours: hard, technical, or long workouts only work when the surrounding days allow you to absorb them.
Example week: Week 2
This week is not a generic template. It is built from the actual training plan entries, and the workout charts use the stored workout data.
1 min @ ?% | 5x variable on / 1 min easy | 3x variable on / 0 min easy | 5x variable on / variable easy + 2 more steps
5 minutes warm-up 5 minutes: 5 times 15 seconds of water polo freestyle (keep your chin above water the whole time), followed by 45 seconds of easy swimming.
No scheduled workout in this real plan week. Use the day to absorb the load and arrive fresh for the next session.
1 min @ ?% | 5x variable on / 1 min easy | 3x variable on / 0 min easy | 1 min @ ?% + 3 more steps
5 minutes warm-up 5 minutes: 5 rounds of 10 seconds water polo freestyle (keeping the chin above water at all times) + 50 seconds easy swimming 10 minutes: 3 rounds of 3 minutes Base/Aerobic Endurance 1 (GA1) with regular forward glances every 2-3 strokes.

How to read the workout charts
The chart is based on the workout data: longer segments take more width, higher intensities sit higher, and harder work is marked with stronger colors. For swim or distance-based segments, the graphic represents the planned sequence rather than GPS data.
Practical execution
What to watch
- Execute the key days precisely instead of making the easy sessions faster.
- Use the plan description as context: equipment, fueling, mobility, and realistic threshold values are part of the training.
- When life or fatigue adds pressure, trim secondary work first and keep the most important session stable.
Training effect
Executed well, the plan improves your ability to absorb the intended stimulus repeatedly. Depending on sport and phase, that means more aerobic stability, better pace durability, stronger technique under fatigue, or more confidence at target effort.
