Rowing Training Zones
All structured rowing training is organized into five zones based on physiological intensity. Each zone targets a specific energy system and produces different fitness adaptations.
The five zones (based on 2K erg pace):
| Zone | Name | 500m Split | Heart Rate | Purpose |
|---|---|---|---|---|
| UT2 | Aerobic base | 2K split + 38-45 sec | 55-65% max HR | Recovery, base aerobic, long rows |
| UT1 | Upper aerobic | 2K split + 24-37 sec | 65-75% max HR | Aerobic development, steady state |
| AT | Anaerobic threshold | 2K split + 12-23 sec | 75-85% max HR | Race-pace endurance, threshold work |
| TR | Transport | 2K split + 6-11 sec | 85-92% max HR | Speed endurance, shorter intervals |
| AN | Anaerobic | 2K split to +5 sec | 92-100% max HR | Race pace and above, power development |
How to use zone training: A typical rowing training week distributes effort as:
- 70-80% UT2 (long, comfortable pieces)
- 10-15% UT1 (moderate steady-state)
- 5-10% AT (threshold intervals)
- 0-5% TR and AN (speed work, sharpening)
2K test protocols:
- Full warm-up: 15-20 minutes of UT2 rowing
- 5 minutes rest
- 2000m all-out effort — even splits or slightly negative (second 1K faster)
- Cool down and record split time
- Test every 6-8 weeks to update zones
Common 2K times and target paces:
| Level | 2K Time (M) | 2K Time (F) | 500m Split |
|---|---|---|---|
| Beginner | 8:00-9:00 | 9:00-10:00 | 2:00-2:15 / 2:15-2:30 |
| Intermediate | 7:00-8:00 | 8:00-9:00 | 1:45-2:00 / 2:00-2:15 |
| Advanced | 6:20-7:00 | 7:20-8:00 | 1:35-1:45 / 1:50-2:00 |
| Elite | Under 6:00 | Under 7:00 | Under 1:30 / Under 1:45 |
Stroke rate by zone:
- UT2: 18-22 spm (focus on ratio and technique)
- UT1: 22-24 spm
- AT: 24-28 spm (race-pace rhythm)
- TR/AN: 28-36+ spm (power and speed)
