Pace Calculator — Calculate Your Running, Walking & Biking Pace

Use this free pace calculator to estimate pace, time, or distance for any activity including running, walking, and biking. Enter any two of the three variables — time, distance, and pace — to instantly calculate the third. Also includes a multipoint pace calculator for segment analysis, a pace converter between miles and kilometers, and a finish time estimator for races in progress.

Tip: Leading zeros are optional in time fields — use 5:3 for 5 minutes 3 seconds, or 50:25 for 50:25.

How to use

  1. Use Pace / Time / Distance tabs: enter any two values to solve the third (flexible time formats like 5:3 or 50:25).
  2. Optionally pick a standard race from the event dropdown to fill distance.
  3. For splits, enter cumulative distance and time at each checkpoint in the multipoint section, then calculate segment paces.
  4. Use the converter for min/mile ↔ min/km, and the finish estimator to project race time from current progress.

How this pace calculator works

This calculator operates in three modes: Pace (from time + distance), Time (from pace + distance), and Distance (from pace + time). Toggle tabs to choose what you want to solve. It works for running, walking, cycling, hiking, or any steady pace activity. You do not need leading zeros in time fields — 5:3 is valid for 5 minutes 3 seconds.

Multipoint pace calculator

Enter cumulative distance and time at each checkpoint. The tool computes pace for each segment between consecutive points — useful for spotting where you slowed down, comparing laps on the same route, or reviewing race splits. You can use up to 12 rows and choose pace per mile or per kilometer.

Pace converter

Convert between minutes per mile and minutes per kilometer using 1 mile = 1.60934 km. To convert min/mile to min/km, divide by 1.60934; min/km to min/mile, multiply by 1.60934.

Finish time estimator

If you are partway through a race or long run, enter distance covered so far, elapsed time, and full distance. The tool assumes you hold your current average pace to the finish — a simple projection, not a prediction of fatigue or surges.

Typical races and world record paces

Elite paces put recreational efforts in context. World-record marathon pace is only a few minutes per mile slower than world-record mile pace — sustained for 26.2 miles.

Training through pace and heart rate

Pace tells you how fast you are moving; heart rate reflects cardiovascular stress. The same pace can feel easier or harder from heat, hills, sleep, or fatigue — heart rate often captures that. Heart rate alone can drift from caffeine, stress, or dehydration, so many athletes use both.

Resting and maximum heart rate

Typical adult resting heart rate is often quoted around 60–100 bpm; trained endurance athletes may be lower. Maximum heart rate is individual; MHR ≈ 220 − age is common but imprecise. Alternatives like Tanaka (208 − 0.7 × age) exist. Lab testing is most accurate.

Example heart rate zones (% of MHR)

  • Zone 1 (recovery): ~50–60%
  • Zone 2 (aerobic base): ~60–70% — often associated with sustainable easy running
  • Zone 3 (aerobic): ~70–80%
  • Zone 4 (threshold): ~80–90%
  • Zone 5 (max): ~90–100%

Aerobic vs. anaerobic exercise

Aerobic work is fueled primarily with oxygen and can be sustained for long periods — the backbone of distance training. Anaerobic efforts outpace oxygen delivery; lactate rises and the effort cannot last long. The lactate threshold is where lactate accumulates faster than clearance; training near it can raise sustainable race pace. A common field test is a hard 30-minute effort using average heart rate over the final ~20 minutes as an estimate of lactate threshold heart rate (individual protocols vary).

How to use pace to improve running

  • Easy runs: Most volume at conversational effort builds base and recovery capacity.
  • Tempo / threshold: Sustained harder efforts to raise the pace you can hold before lactate spikes.
  • Intervals: Short faster reps for speed and VO₂; balance with easy days.
  • Long runs: Endurance and durability for half marathon and marathon goals.
  • Progressive overload: Gradual increases in distance or intensity; ~10% weekly mileage bumps are a common cautious guideline.

Common race distances

  • 5K (~3.1 mi): Popular entry race; recreational finishes often span a wide range (e.g. ~25–35+ minutes).
  • 10K (~6.2 mi): Needs aerobic discipline; negative splits are easier when the first half is controlled.
  • Half marathon (~13.1 mi): Often 10–16 weeks of structured training for newer runners.
  • Marathon (~26.2 mi): Long build; pacing the first half conservatively is a common tactic.

Frequently asked questions

Pace math, conversions, training zones, and race goals.

How do I calculate running pace?

Divide your total time by your distance. For time in minutes: pace (min/mile) = total minutes ÷ miles. For example 50 minutes for 5 miles = 10:00 per mile pace. For hours and minutes convert to total minutes first: 1 hour 45 minutes = 105 minutes, 105 ÷ 13.1 miles ≈ 8:01/mile half marathon pace. Or use the calculator above — enter time and distance to get pace instantly.

What is a good running pace?

It depends entirely on your fitness level and the distance. For a 5K a good recreational pace is often roughly 8:00–10:00/mile for men and 9:00–11:00/mile for women. For a marathon 9:00–11:00/mile can be a solid recreational pace. Elite marathoners hold near 4:41/mile for 26.2 miles — faster than many people can run a single mile. Focus on improving relative to your own baseline rather than comparing to others.

How do I convert min/mile to min/km?

Divide your min/mile pace by 1.60934 to get min/km. For example 8:00/mile ÷ 1.60934 ≈ 4:58/km. Or use the pace converter on this page to convert any pace between the two units.

How fast is a 7 minute mile?

A 7:00/mile pace equals about 4:21/km. At this pace a 5K takes roughly 21:45, a 10K about 43:30, a half marathon about 1:32:00, and a marathon about 3:03:30. A 7-minute mile is faster than many recreational runners but well below competitive or elite levels.

What pace do I need to run a sub-2-hour half marathon?

To finish a half marathon (13.1 miles) in under 2 hours you need to average faster than about 9:09/mile (5:41/km). This is a common goal for recreational runners. Use the pace calculator to find exact splits for any finish-time goal.

What is the difference between aerobic and anaerobic running?

Aerobic running uses oxygen to produce energy and can be sustained for long periods — easy to moderate intensity forms the base of endurance training. Anaerobic running is high intensity where oxygen delivery cannot keep up; muscles produce lactate, and that pace can only be held for short periods. Most distance training is aerobic, with smaller amounts of threshold and speed work.

What is the lactate threshold and why does it matter for runners?

The lactate threshold is the intensity where lactate accumulates in the blood faster than it can be cleared. Below it, effort feels hard but sustainable; above it, lactate rises quickly and you slow down. Training at and around threshold pace raises the speed you can sustain aerobically — improving race times from 5K to marathon.

How do I use heart rate zones for running training?

Estimate maximum heart rate (e.g. 220 − age, knowing it is imprecise) and set zones as percentages. Many programs put easy running around 60–70% MHR, tempo and threshold around 70–85%, and intervals above that. A large share of weekly volume is often easy aerobic running. Heart rate monitors help you stay in the intended zone; combine with pace because heat, fatigue, and stress also move heart rate.

Who uses this calculator

This pace calculator is used by runners calculating pace from recent training runs or races, athletes planning goal pace for upcoming events, coaches analyzing segment times for training feedback, beginners estimating how long a 5K or 10K will take at their current fitness, cyclists and walkers tracking activity pace, triathletes switching between disciplines and units, and anyone converting between minutes per mile and minutes per kilometer.
