Enter your target 5K finish time (hours, minutes, seconds) and preferred pace unit (min/mile or min/km) to get your required pace per mile, pace per kilometer, and average speed. The 5K Pace Calculator also shows a split breakdown chart so you can plan your race strategy and hit your goal time.

A 5K pace calculator takes your target finish time and tells you exactly how fast you need to run each kilometer or mile to achieve that goal. It removes the guesswork from race planning so you can start at the right speed and avoid burning out early or finishing with too much energy left.
The calculator divides the 5K distance (5 kilometers or 3.1 miles) by your total target time in minutes to produce your required pace per unit. It also calculates your average speed in both km/h and mph, and generates per-kilometer split targets so you know your checkpoints during the race.
A good 5K time depends on your age, fitness level, and experience. For recreational runners, finishing in 25–35 minutes is considered solid. Competitive club runners typically aim for 18–22 minutes, while elite runners finish under 15 minutes. For first-timers, simply completing the race is a great achievement.
To finish a 5K in 25 minutes, you need to maintain a pace of exactly 5:00 per kilometer or approximately 8:03 per mile. That's an average speed of 12 km/h (7.5 mph). Using even splits across all 5 kilometers is the most reliable strategy for hitting this target.
An 18-minute 5K requires a pace of 3:36 per kilometer or about 5:47 per mile. This is a competitive benchmark and typically requires a structured training program including tempo runs, interval sessions, and consistent weekly mileage over several months.
Even pacing — running each kilometer at the same speed — is generally the most effective strategy for recreational runners. Some experienced runners use a negative split approach, running the second half slightly faster than the first. Avoid going out too hard in the first kilometer, as it leads to fatigue that is difficult to recover from over such a short distance.
Pace in running refers to the time it takes to cover a set distance, usually expressed as minutes per kilometer (min/km) or minutes per mile (min/mi). It is the inverse of speed — a lower pace number means you're running faster. Most GPS watches and running apps display pace in real time during a run.
To convert pace per kilometer to pace per mile, multiply your min/km value by 1.60934. For example, a 5:00/km pace equals approximately 8:03/mile. Our calculator performs this conversion automatically and displays both values side by side.
