What Is Running Pace?

Running pace is how long it takes you to cover a set distance — typically expressed as minutes per kilometre (min/km) or minutes per mile (min/mi). It is the fundamental metric for runners at every level.

Understanding pace helps you:

  • Set realistic race finish time goals
  • Train at the right intensity for each workout
  • Compare your performance across different distances
  • Track improvement over time
Use our Running Pace Calculator to calculate pace, finish time, or distance instantly.

The Three Pace Calculations

There are three interrelated calculations — if you know two values, you can find the third.

1. Calculate Pace from Distance and Time Formula: Pace = Time ÷ Distance

Example: You ran 10km in 52 minutes. Pace = 52 ÷ 10 = 5:12 per km

2. Calculate Finish Time from Pace and Distance Formula: Time = Pace × Distance

Example: You run at 5:30/km and want to know your half marathon finish time. Time = 5:30 × 21.1 = 116 minutes = 1 hour 56 minutes

3. Calculate Distance from Pace and Time Formula: Distance = Time ÷ Pace

Example: You ran for 45 minutes at 6:00/km. Distance = 45 ÷ 6 = 7.5 km

Standard Race Distances and Paces

5K (5 kilometres)

  • Beginner finish time: 35–45 minutes (7:00–9:00/km)
  • Intermediate: 25–35 minutes (5:00–7:00/km)
  • Advanced: 18–25 minutes (3:36–5:00/km)
  • Elite: Under 14 minutes (under 2:48/km)
10K (10 kilometres)
  • Beginner: 70–90 minutes (7:00–9:00/km)
  • Intermediate: 50–70 minutes (5:00–7:00/km)
  • Advanced: 38–50 minutes (3:48–5:00/km)
  • Elite: Under 28 minutes (under 2:48/km)
Half Marathon (21.1km)
  • Beginner: 2:30–3:00 (7:06–8:32/km)
  • Intermediate: 1:50–2:30 (5:13–7:06/km)
  • Advanced: 1:20–1:50 (3:48–5:13/km)
  • Elite: Under 1:00 (under 2:50/km)
Marathon (42.2km)
  • Beginner: 5:00–6:00 (7:06–8:32/km)
  • Intermediate: 3:30–5:00 (4:58–7:06/km)
  • Advanced: 2:45–3:30 (3:54–4:58/km)
  • Elite: Under 2:10 (under 3:05/km)

Converting Between Pace and Speed

Pace (min/km) and speed (km/h) are different ways of expressing the same thing.

Convert pace to speed: Speed (km/h) = 60 ÷ Pace (min/km)

Example: 5:30/km pace Speed = 60 ÷ 5.5 = 10.9 km/h

Convert speed to pace: Pace (min/km) = 60 ÷ Speed (km/h)

Example: Running at 12 km/h Pace = 60 ÷ 12 = 5:00/km

Quick reference:

  • 6 km/h = 10:00/km (comfortable walk/jog)
  • 8 km/h = 7:30/km (easy jog)
  • 10 km/h = 6:00/km (moderate run)
  • 12 km/h = 5:00/km (comfortably hard)
  • 14 km/h = 4:17/km (hard effort)
  • 16 km/h = 3:45/km (very hard)
  • 18 km/h = 3:20/km (near-sprint)

Converting km/min Pace to Miles/min Pace

Many races and training plans use miles rather than kilometres.

1 mile = 1.60934 km

To convert min/km to min/mile: multiply by 1.60934 Example: 5:00/km × 1.60934 = 8:03/mile

To convert min/mile to min/km: divide by 1.60934 Example: 9:00/mile ÷ 1.60934 = 5:35/km

Common pace conversions:

  • 4:00/km = 6:26/mile
  • 4:30/km = 7:15/mile
  • 5:00/km = 8:03/mile
  • 5:30/km = 8:51/mile
  • 6:00/km = 9:39/mile
  • 6:30/km = 10:28/mile
  • 7:00/km = 11:16/mile

Training Paces: Not All Runs Should Be at Race Pace

One of the most common running mistakes is running too fast on easy days. Structured training uses different paces for different purposes:

Easy pace (60–75% max heart rate) Conversational — you can speak in full sentences. This is where 70–80% of your weekly mileage should be run. Builds aerobic base, promotes recovery, and reduces injury risk.

Approximately 60–90 seconds per km slower than your 5K race pace.

Tempo pace (80–90% max heart rate) Comfortably hard — you can speak in short phrases but not hold a conversation. Improves lactate threshold (the pace you can sustain for roughly 60 minutes). Used in tempo runs of 20–40 minutes.

Approximately 25–40 seconds per km slower than your 5K race pace.

Interval pace (90–100% max heart rate) Hard to very hard — speaking is difficult. Used in short intervals (400m–1600m) with recovery between. Improves speed and VO2 max.

Approximately at or faster than your 5K race pace.

Long run pace 10–20% slower than your easy pace. Emphasis on time on feet rather than speed. Builds endurance and mental durability.

Predicting Race Times Across Distances

You can estimate your race time at one distance from a known result at another using the following formula (Riegel's formula):

T2 = T1 × (D2 ÷ D1)^1.06

Where T1 is your known time, D1 is that distance, T2 is the predicted time, and D2 is the target distance.

Approximate conversion table (from 5K time):

  • 5K 20:00 → 10K ~41:45, Half Marathon ~1:33, Marathon ~3:16
  • 5K 25:00 → 10K ~52:15, Half Marathon ~1:57, Marathon ~4:05
  • 5K 30:00 → 10K ~62:45, Half Marathon ~2:21, Marathon ~4:54
  • 5K 35:00 → 10K ~73:15, Half Marathon ~2:44, Marathon ~5:42
These are predictions — actual performance depends on specific training, terrain, conditions, and individual strengths across distances.

Calories Burned Running at Different Paces

Running pace significantly affects calorie burn. Faster running burns more calories per minute but you cover distance faster too.

Per kilometre, calorie burn is relatively constant regardless of pace for the same body weight. The main variable is body weight.

Approximate calories burned per kilometre by body weight:

  • 60 kg: ~55–60 kcal/km
  • 70 kg: ~65–70 kcal/km
  • 80 kg: ~75–80 kcal/km
  • 90 kg: ~85–90 kcal/km

Frequently Asked Questions

  • What is a good running pace for a beginner?
There is no universal "good" pace for beginners — the right pace is one where you can run comfortably without stopping. For most beginners this is between 7:00 and 9:00 per kilometre (about 11–14 min/mile). Focus on completing the distance before worrying about pace.
  • How do I improve my running pace?
Consistency is more important than any single workout. Run regularly (3–4 times per week minimum), include one longer run each week, and gradually add interval training as your fitness improves. Pace improvement typically follows naturally from consistent training.
  • What pace should I run a half marathon?
A good strategy is to run your first half marathon at a pace you can sustain for the entire distance — which for most people is 15–30 seconds per km slower than your 10K race pace. Use our Running Pace Calculator to plan your split times.
  • How long does it take to run 5km?
Average 5K time for recreational runners is approximately 30–35 minutes (6:00–7:00/km). Beginners may take 40–50 minutes. Competitive club runners target under 20 minutes.
  • Is 6 minutes per km a good pace?
6:00/km (approximately 9:39/mile) is a solid recreational running pace. It equates to a 30-minute 5K, 60-minute 10K, and approximately 2:07 half marathon. For a beginner it is an excellent goal pace. For an experienced runner it would be an easy recovery pace.
