VDOT & Training Pace Calculator (Jack Daniels Method)
Enter a recent race time to compute your VDOT and Jack Daniels training paces for 2026. Accurate for US runners using miles & kilometers.
🏃 Training paces (Jack Daniels' Running Formula)
* Based on Dr. Jack Daniels' Running Formula (3rd/4th edition). Paces shown in min/mile and min/km. VDOT is computed with the Daniels–Gilbert equations: the oxygen cost of your race speed, VO₂ = −4.60 + 0.182258·v + 0.000104·v² (v in metres per minute), divided by the fraction of VO₂max you can sustain for the race time, 0.8 + 0.1894393·e−0.012778·t + 0.2989558·e−0.1932605·t (t in minutes).
What is the Jack Daniels Running Calculator? (VDOT explained)
The jack daniels running formula calculator uses your race performance to calculate a VDOT value — a number that represents your running economy and aerobic capacity. Unlike generic pace calculators, the dr jack daniels running calculator tailors every training intensity (Easy, Threshold, Interval, Repetition) to your unique fitness level.
- Easy (E): Recovery & base building (65-79% of vVO2max)
- Marathon (M): Specific endurance for 26.2 miles
- Threshold (T): “Comfortably hard” – improves lactate clearance
- Interval (I): VO2max development, 3-5min repeats
- Repetition (R): Speed and running economy, short fast reps
Our jack daniels running calculator excel alternative brings the same precision directly to your browser. In 2026, the VDOT system remains the most science-backed approach to personalized running plans.

Exclusive: 2026 training insights using Jack Daniels running plan calculator
Unlike generic plans, the jack daniels running plan calculator adjusts as you improve. Here’s how top US coaches apply the VDOT system in 2026:
5-step VDOT progression checklist (2026 edition):
- Run a recent race (time trial: 5K or 10K works best).
- Enter your time into the running calculator jack daniels above → get VDOT.
- Use the provided E, T, I, R paces for quality workouts.
- Apply the “80/20 rule”: 80% easy running at E pace, 20% at T/I/R.
- Retest every 6 weeks — track improvements via VDOT score.
With the jack daniels running distance calculator you can also predict race times for other distances: just find your VDOT and match equivalent performance. For example, a VDOT of 48 predicts a 5K around 17:30 and a half-marathon ~1:21:00.
