Navy PRT Cardio: Run vs Row vs Swim vs Bike
Choosing your PRT cardio event is strategic, not just preference. The 1.5-mile run, 2-km row, 500-yd swim, and 12-minute stationary bike all score the same tiers — but your body's strengths determine which gets you to Outstanding fastest.
Quick Comparison
| Event | Best For | Toughest On |
|---|---|---|
| 1.5-mile run | Lean runners with aerobic base | Heavier Sailors, joint issues |
| 2-km row | Strong back/legs, good aerobic | Technique-poor rowers (huge loss) |
| 500-yd swim | Strong swimmers, good technique | Anyone who didn't grow up in pools |
| 12-min bike | Leg-dominant athletes, injured runners | Weak cyclists (low power output) |
1.5-Mile Run
The default event — most Sailors take it. If you're 170 lb or under and have a reasonable aerobic base, this is your fastest path to Outstanding.
Train: 4 runs per week — one interval, one tempo, two easy. Build from ~10 min Zone 2 to 45 min over 8 weeks.
2-km Row
The best choice for Sailors with heavy lower-body strength or those with running injuries. Technique matters enormously — a poor rower loses 30+ seconds to a trained rower at the same fitness level.
Key technique: Legs → back → arms on the drive. Arms → back → legs on the recovery. Never just pull with arms.
Train: 2 sessions per week. Interval: 6x 500m at goal pace, 90s rest. Steady: 20 minutes continuous at 2-km pace + 10 seconds.
500-yd Swim
Best if you grew up swimming or have solid technique from a past life. Stroke choice matters — breaststroke and sidestroke are most efficient for the PRT. Freestyle without real training will burn you out fast.
Train: 3 pool sessions per week. Technique drills + interval sets (200-yd repeats at goal pace).
12-Minute Bike (Calories)
Calorie-scored event using an Assault Bike, Concept2 BikeErg, or similar ergo. Best for Sailors with strong legs and minimal running experience.
Key: Maintain a steady RPM 80-90 for the full 12 min. Calorie output = RPM × time + power. Don't go out too hard — you'll gas in 4 minutes.
How to Decide
Test each event once over 4 weeks. Record your classification (Outstanding/Excellent/Good/Satisfactory). Pick the one that:
- Scored the highest
- You can improve fastest
- Matches your body type and injury history
Sailors over 200 lb or with knee issues: skip the run. Lean ex-runners: don't go fight tropical climate row tests.

Switching Events Mid-Training
You can. But give yourself 6+ weeks of dedicated training on the new event before testing for record. Transferring aerobic base works; transferring technique doesn't.
