10K Pace Calculator
Calculate the exact pace for your 10K goal time with per-km, per-mile, or 5K checkpoint splits — bridging 5K speed and half marathon endurance.
Your target 10K finish time. A 50-minute 10K requires 5:00 /km (8:03 /mi).

Calculate the exact pace for your 10K goal time, with per-km, per-mile, or 5K checkpoint splits — bridging 5K speed and half marathon endurance. A 10K is 10.0 km (6.21371 mi) — 25 laps of a 400 m track — and is the most common road event above 5K, rewarding both aerobic endurance and near-threshold pace holding. Enter your target finish time below, choose a split interval, and the calculator returns the required pace per km, per mile, speed in km/h, and a full split ladder. Further down the page you'll find a goal-time reference table, percentile landscape from major road events, 5K → 10K scaling, training-week guidance, and age-group benchmarks.
pace_km = goal_time ÷ 10.0 · split_5k = goal_time ÷ 2- pace_km
- = Required pace in minutes per kilometre
- pace_mi
- = Required pace in minutes per mile (pace_km × 1.60934)
- goal_time
- = Target 10K finish time in decimal minutes
- 10.0
- = 10K race distance in kilometres (6.21371 mi)
- split_5k
- = Time at the 5 km halfway mark (even-pace target)
Worked example — 50:00 10K
- goal_time = 50.000 min
- pace_km = 50.000 ÷ 10.0 = 5.000 min/km → 5:00/km
- pace_mi = 5.000 × 1.60934 = 8.047 min/mi → 8:03/mi
- speed_kmh = 60 ÷ 5.000 = 12.00 km/h
- split_5k = 50.000 ÷ 2 = 25.000 min → 25:00
- = 5:00/km (8:03/mi) · 12.00 km/h · 25:00 at 5K
Formulas F1 (pace = time ÷ distance), F2 (pace ↔ speed), F13 (splits) — site/03-globals.md §formulas. For a negative split strategy, target slightly slower than pace_km for the first 5K and faster for the second — see the Negative Split Pace Calculator.

From 5K to 10K: Scaling Your Pace
5K
- Distance: 5.0 km (3.10686 mi) — 12.5 track laps
- Energy system: VO2 max; uncomfortable from 5 min in
- Pace: Your fastest sustainable over 15–25 min
- Training: 6–10 weeks, peak long run 8–12 km
- Recovery: 2–3 days for recreational runners
Shorter, sharper, and forgiving of pacing mistakes
10K
- Distance: 10.0 km (6.21371 mi) — 25 track laps
- Energy system: Threshold; sustainable but unrelenting
- Pace: Typically 10–15% slower per km than 5K
- Training: 8–12 weeks, peak long run 12–16 km
- Recovery: 4–7 days before quality sessions
Twice the distance punishes a fast start — even pacing matters more
Building 10K Fitness
Threshold runs
20–40 min at threshold pace (comfortably hard, roughly 10K–15K race effort), or 2–3 × 10–15 min with short jog recovery. The single most effective session for 10K-specific fitness.
VO2 max intervals
5–8 × 1000 m or 6–10 × 800 m at 5K–3K pace with equal-duration jog recovery. Expands the ceiling — once a week during a dedicated 10K build.
Long aerobic runs
90–120 minutes easy, building to 15–18 km. Critical for the last 3 km of a 10K, when aerobic reserve matters more than top speed.
Race-pace simulation
4 × 2 km at 10K goal pace with 3-minute jog recovery, 2–3 weeks out. Grounds pacing instinct and confidence without the recovery cost of a full tune-up race.
