How to Use

  1. 1 Choose your mode — 'Pace from finish time' or 'Finish time from pace'
  2. 2 Enter your distance and select the unit (km, miles, or metres)
  3. 3 For pace-from-time: enter your finish time in hours, minutes, seconds
  4. 4 For time-from-pace: enter your target pace in minutes and seconds per km
  5. 5 See your pace per km, pace per mile, speed, and projected splits instantly

Features

  • Two modes — derive pace from time, or predict finish time from pace
  • Pace shown in both min/km and min/mile simultaneously
  • Speed shown in both km/h and mph
  • Projected splits for 400m, 800m, 1K, 1 mile, 5K, 10K, 15K, half-marathon, marathon
  • Supports kilometres, miles, and metres as distance input
  • Informational only — for training plans consult a certified running coach

Why it Matters

Knowing your pace makes you a smarter runner. Going out too fast in a race causes late-race fade. Splits let you check whether you are on target at each waypoint. For training, pace zones determine whether a run builds aerobic base or becomes junk mileage.

Use Cases

Race Day Planning

Set a target finish time and see the exact pace you must maintain per km

Training Plan Design

Calculate easy, tempo, and interval paces from a recent race time

Post-Race Analysis

Enter your actual time to understand overall pace and where you gained or lost

Treadmill Users

Convert a target pace to km/h or mph for treadmill speed settings

What this tool does

Enter a distance and finish time to calculate your pace per kilometre and mile. Or enter a pace and distance to predict your finish time. Projected splits show estimated times at standard race waypoints from 400m to the full marathon.

Pace basics

Pace is how long it takes to cover one unit of distance — typically one kilometre or one mile. A pace of 5:00 min/km means each kilometre takes exactly 5 minutes. At that pace a 10K takes 50:00 and a half-marathon takes approximately 1:45:34.

Pair this with the Heart Rate Zones calculator to match pace to training zones, or Calories Burned to estimate energy expenditure per run.

Frequently Asked Questions

What is a good running pace for beginners?
A comfortable beginner pace is typically 8:00–10:00 min/km (13–16 min/mile). At this pace a 5K takes 40–50 minutes. Pace is highly individual — what matters is consistency and gradual improvement rather than hitting any specific number. Consult a certified running coach for a personalised training plan.
How do I convert min/km to km/h?
Divide 60 by your pace in minutes. A pace of 5:00 min/km = 60 ÷ 5 = 12 km/h. A pace of 6:00 min/km = 60 ÷ 6 = 10 km/h. The tool calculates this automatically.
What is a negative split?
Running the second half of a race faster than the first. It is widely considered the most efficient racing strategy — you conserve energy early and accelerate when others fade. Most world records are set with negative or even splits.
How accurate are the projected splits?
Splits assume perfectly even-effort pacing throughout the race. Real splits vary with hills, weather, fatigue, and race tactics. The tool gives a mathematical baseline — adjust for course conditions and your personal race strategy.
