Enter your pace (minutes and seconds per km or per mile) and your distance to calculate your total finish time. The Pace to Time Calculator shows your result in hours, minutes, and seconds — plus estimated finish times for popular race distances like 5K, 10K, half marathon, and marathon.

A pace to time calculator converts your running pace — expressed in minutes per kilometre or minutes per mile — into a total finish time for any given distance. You simply enter your pace and how far you plan to run, and it tells you how long the run will take.
The calculator multiplies your pace (in seconds per unit distance) by the total distance in matching units. For example, a pace of 5:30 per km over 10 km equals 55 minutes total. If your pace unit differs from your distance unit, the calculator automatically converts between km and miles (1 mile = 1.60934 km).
A good 5K time varies widely by fitness level. Recreational runners often finish in 25–35 minutes (5:00–7:00 min/km or 8:00–11:00 min/mile). Competitive club runners typically aim for under 20 minutes (~4:00 min/km), while beginners may target 35–45 minutes. Any pace that gets you to the finish line is a good pace.
To finish a marathon (42.195 km / 26.219 miles) in exactly 4 hours, you need to maintain a pace of approximately 5:41 per km or 9:09 per mile. The calculator will show this automatically — just enter 4-hour pace values and select the marathon distance.
Min/km means how many minutes it takes you to run one kilometre, while min/mile measures the same per mile. Since one mile equals 1.60934 km, a pace of 5:00 min/km is equivalent to roughly 8:03 min/mile. The calculator handles this conversion automatically when your pace unit and distance unit differ.
A consistent, even pace is widely considered the most effective race strategy. Use this calculator to determine your target pace for your goal finish time, then aim to run every kilometre or mile at that pace. Many runners also benefit from a slight negative split — starting slightly slower and finishing faster.
Yes. Enter your pace and then choose your distance. Common race distances are 5K (5 km), 10K (10 km), half marathon (21.0975 km), and full marathon (42.195 km). The results table below the calculator also shows estimated finish times for all these distances simultaneously based on your entered pace.
The calculator assumes a perfectly constant pace across the entire distance. In reality, factors like hills, weather, fatigue, congestion at the start, and hydration stops all affect your real time. Use the estimate as a planning guide and build in a small buffer for race conditions.
