Description
This pace and time calculator helps runners accurately plan their race goals and training workouts. Simply enter a distance and either your total time or your desired pace, and the tool will compute the missing value. Use it to set interval targets, predict finish times, or see how small pace adjustments affect your overall performance.
Typical finish times vary depending on experience, age, and fitness level. Beginner runners often complete 5 km in 25–35 minutes, while more experienced athletes aim for 20 minutes or faster. Half-marathon times commonly range from 1:45 to 2:15 hours, and marathon finish times often fall between 3:30 and 4:30 hours.
Frequently Asked Questions
What is a pace calculator?
A pace calculator is a tool that allows runners to calculate their race times based on a given pace, or vice versa. It predicts how small changes in pace impact overall finish time for any distance.
How do I use this pace calculator?
Select your unit (km or miles), enter the distance, and fill in either the total time or the desired pace. Click "Calculate" to automatically fill in the missing field and display your results.
How does the calculator work?
The calculator multiplies pace (minutes per unit) by distance to determine total time, or divides total time by distance to compute pace. It does not account for factors like fatigue, terrain, or weather conditions.
What is a good 5K finishing time?
For recreational runners, 25–30 minutes is a solid goal. More competitive runners may target 20 minutes or less. Ultimately, a good time depends on your training background.
What pace is required for a 4-hour marathon?
A marathon is 42.195 km. To finish in 4 hours, you need an average pace of approximately 5:41 min/km (about 9:09 min/mile).
How do I read a marathon pace chart?
A marathon pace chart lists pace (min/km or min/mi) alongside corresponding finish times for 42.195 km. Match your target pace to its finish time to set realistic race goals.
How do I read a half-marathon pace chart?
Similar to the marathon chart, it shows pace versus finish time for 21.0975 km. Use it to plan splits and maintain consistent effort throughout the race.
How do I read a 5K pace chart?
It displays pace (min/km or min/mi) against completion times for 5 km. Ideal for assessing current fitness and setting training benchmarks.
