VMA & VDOT Running Pace Calculator

VMA & VDOT Running Pace Calculator

Enter your most recent race time and instantly get your 5 personalized training paces using Jack Daniels' VDOT method

Calculate my paces for free

Knowing your exact training paces is the foundation of any structured plan. Most runners go too fast on easy days and not fast enough on hard days — and wonder why they stagnate. RunRun's VDOT calculator solves this in under a minute. Enter a recent race time — 5K, 10K, half marathon or marathon — and the calculator derives your VDOT score (Jack Daniels' internationally recognized formula) and generates your five precise training paces. Free, no Strava or GPS watch required.

Why choose RunRun?

Jack Daniels VDOT Formula

The calculator is built on physiologist Jack Daniels' VDOT method — the gold standard in running science. Your paces are calculated scientifically, not guessed.

5 Training Paces Derived

One race time generates five precise zones: easy pace (aerobic base), marathon pace, threshold/tempo pace, VO2max pace (intervals), and speed pace (short reps).

All Race Distances Accepted

The calculator accepts performances from 5K, 10K, half marathon or marathon. Longer reference distances give the most accurate endurance paces.

Results in 30 Seconds

No pre-setup needed. Enter your race time and get your paces immediately. The calculator is available directly from your RunRun account.

Free – No Strava or Garmin Needed

Unlike many tools, RunRun's calculator doesn't require a GPS watch or connected account. A manually entered race time is all you need.

VDOT History Tracked

Every calculation is saved to your profile. Track your VDOT score over time and compare paces before and after each training block.

How to use the calculator in 5 steps

W1

Choose your reference distance

Select the distance for which you have a recent, reliable race time: 5K, 10K, half marathon or marathon. A time from the last 8 weeks gives the most accurate paces.

  • •5K: ideal for runners early in their progression
  • •10K: the most widely used reference distance — best balance of precision and accessibility
  • •Half marathon: recommended for refining long-distance paces
  • •Marathon: best for marathon-specific race preparation
W2

Enter your race time

Type in your finish time in hours:minutes:seconds. RunRun automatically computes your average speed, your min/km pace, and derives your VDOT score.

  • •Example: 10K in 50:00 → average speed 12.0 km/h
  • •Use an actual race time, not a training run
  • •Avoid times run in extreme heat or on hilly courses
  • •A recent race with a strong effort is better than an old PR
W3

Discover your VDOT score

VDOT is a numeric index reflecting your overall aerobic fitness. The same VDOT predicts consistent performances across all distances.

  • •Example: 10K in 50:00 → VDOT ≈ 39
  • •VDOT 30-35: beginner to intermediate level
  • •VDOT 40-50: intermediate to advanced
  • •VDOT 55+: competitive level (sub-40 on 10K)
W4

Your 5 training paces generated

For a VDOT of 39 (10K in 50:00), here are the five calculated paces. Each zone targets a specific physiological adaptation.

  • •Easy pace (E): ~6:30/km — aerobic base, 70-80% of weekly mileage
  • •Marathon pace (M): ~5:45/km — long run specific
  • •Threshold pace (T): ~5:10/km — tempo runs, 20-40 min continuous
  • •VO2max pace (I): ~4:40/km — 800m-1000m-1200m intervals
  • •Speed pace (R): ~4:10/km — short reps 200m-400m
W5

Build your full training plan

The calculator is your starting point. RunRun can generate a complete AI training plan that automatically integrates your VDOT paces into every session.

  • •Recalculate paces after every significant race or time trial
  • •Update if your VDOT increases by 2 or more points
  • •Generate an AI plan that uses these paces in every structured session
  • •Review your VDOT history to see real, measurable progress

Tips for training with VDOT paces

1

Easy pace is the most important

Most runners go too fast on easy days. Your VDOT easy pace may feel very slow — that's intentional. Respect it to maximize aerobic adaptations without accumulating unnecessary fatigue.

2

Use only one hard zone per week

Threshold (T), intervals (I) and speed (R) are high-intensity zones. Combine at most one per week. The rest of your weekly mileage should be easy pace (E).

3

Recalculate after every race

Your VDOT changes as you improve. After every competition or time trial, rerun the calculator. Outdated paces hold back your hard sessions and inflate your easy ones.

4

Choose a reliable, representative time

A time run in bad conditions (heat, hills, pre-fatigue) underestimates your real VDOT. Use a time that truly reflects your current fitness.

5

Calibrated marathon pace is a game-changer

Most marathon runners go out too fast. Your VDOT-derived M pace accounts for your real fitness level. Stick to it through the first 30 km — it's the best race strategy for any distance.

What is VMA and how is it different from VDOT?
VMA (Vitesse Maximale Aérobie, or vVO2max) is the running speed at which your oxygen consumption reaches its maximum — your aerobic ceiling. VDOT is a composite index developed by Jack Daniels that predicts performance across distances from a single race time. In practice, VDOT is easier to obtain and directly generates all 5 training zones. RunRun uses the VDOT method, with VMA embedded as an underlying parameter.
How does RunRun calculate my training paces?
RunRun applies Jack Daniels' VDOT formula: from your race time over a given distance, it derives your aerobic capacity (VDOT score), then calculates 5 training paces using the VO2max percentages that correspond to each physiological zone — easy at 59-74%, threshold at 83-88%, intervals at 95-100%, etc.
Do I need to connect Strava or Garmin to use the calculator?
No. RunRun's VDOT calculator works entirely from a manually entered race time. No Strava connection, no GPS watch, no syncing required. Enter your distance and finish time — RunRun does the rest.
Is the pace calculator free?
Yes, the VDOT calculator is completely free for all RunRun users. No premium subscription is required to access your training paces or your VDOT score history.
How often should I recalculate my paces?
Recalculate after every significant performance: an official race, a 5K or 10K time trial, or after a 6-8 week training block. During active progression phases, a monthly update is ideal. Outdated VDOT scores can cause you to train too slowly at high intensity or not slowly enough on easy days.
Are my VDOT paces suited to my target race?
Yes. VDOT derives optimal training paces based on your current fitness, regardless of your goal. If you're targeting a marathon, your calculated M pace is your race pace target. If you're racing a 10K, T and I zones will be your primary work zones. RunRun's AI training plan automatically distributes these zones based on your goal and chosen preparation length.
