VDOT Running Calculator
Calculate your VDOT score and get equivalent race times plus training paces. Based on Jack Daniels' proven methodology used by elite coaches worldwide.
What is VDOT?
VDOT is a measure of your running fitness developed by legendary coach Jack Daniels. It's not actually your VO2max (the V doesn't stand for anything specific), but rather a calculated value that represents your current running ability.
The beauty of VDOT is that it accounts for both your aerobic capacity AND your running economy, giving you a single number that predicts performance across all race distances.
How VDOT Works
Your VDOT score is derived from a recent race performance. From that score, you get:
- Equivalent race times - What you could theoretically run at other distances
- Training paces - Exact paces for each type of workout
The Five Training Paces
| Pace | % of VDOT | Purpose |
|---|---|---|
| Easy (E) | 59-74% | Recovery, base building |
| Marathon (M) | 75-84% | Marathon-specific endurance |
| Threshold (T) | 83-88% | Lactate threshold improvement |
| Interval (I) | 95-100% | VO2max development |
| Repetition (R) | 105-110% | Speed and economy |
Why VDOT Beats Generic Pace Calculators
Most pace calculators use simple formulas. VDOT is based on decades of research correlating oxygen uptake, running economy, and race performances across thousands of runners.
Key Advantages
- Accounts for running economy - Not just raw VO2max
- Validated across distances - From 1500m to marathon
- Used by elite coaches - The methodology behind countless Olympic medals
- Provides training paces - Not just race predictions
Important Notes
VDOT Assumes Equal Training
Your predicted times assume you've trained appropriately for each distance. A pure 5K runner may not hit their marathon VDOT prediction without specific marathon training.
Use Recent Races
VDOT should be calculated from races within the last 4-6 weeks. Older races may not reflect your current fitness.
Adjust for Conditions
Standard VDOT assumes ideal racing conditions:
- Temperature: 50-60°F (10-15°C)
- Course: Flat, fast surface
- Altitude: Near sea level
Adjust expectations for heat, hills, or altitude.
VDOT Ranges
| VDOT | 5K Time | Marathon Time | Level |

| 40 | 22:12 | 3:36 | Intermediate |
| 50 | 17:30 | 2:50 | Advanced |
| 60 | 14:26 | 2:21 | Elite |
| 70 | 12:09 | 2:00 | World Class |
