Our free pace calculator is an essential tool for runners and walkers of all levels. Use it to calculate your running pace from a distance and time, find your finish time for a given pace and distance, or determine the distance you can cover at a given pace in a set time. The calculator also shows projected race finish times for popular race distances.

Whether you are training for your first 5K, preparing for a half marathon, or chasing a marathon personal best, the pace calculator helps you plan your training and race strategy with precision. It supports both miles and kilometres, making it useful for runners in the USA and Canada.

How to Use the Pace Calculator

The pace calculator has three modes — here is how each one works:

1. Calculate Pace — Enter a distance and time to find your pace per mile or kilometre.
2. Calculate Finish Time — Enter a distance and your target pace to find your projected finish time.
3. Calculate Distance — Enter a time and pace to find how far you can run.
4. Select your distance unit (miles or km), fill in the two known values, and click Calculate.

When Should You Use a Pace Calculator?

Use the pace calculator during race planning to set a realistic pace target based on your current fitness level. In particular, it is helpful for pacing your first marathon or half marathon — starting too fast is the most common race-day mistake and leads to hitting the wall in the later miles.

Furthermore, use the pace calculator during training to ensure your easy runs are truly easy (typically 60–90 seconds per mile slower than race pace). Additionally, the projected finish times for 5K, 10K, half marathon, and full marathon let you compare your performance across different distances.

Running Tips for Better Performance

Here are practical tips to improve your running pace and race times:

• Run most miles at an easy pace — 80% of your weekly mileage should be at a comfortable, conversational pace. Only 20% should be at high intensity.
• Build mileage gradually — Increase weekly mileage by no more than 10% per week to reduce injury risk.
• Include tempo runs — Running at your lactate threshold pace once a week improves your ability to sustain faster paces in races.
• Practice your race pace — Run at your target race pace in training so your body learns the specific effort level.
• Fuel and hydrate properly — For runs over 60–90 minutes, consume carbohydrates and fluids during the run to maintain energy and pace.

Frequently Asked Questions About the Pace Calculator

What is a good running pace?

For recreational runners, a pace of 9–11 minutes per mile (5:30–6:50 per km) is common. Beginning runners may start at 12–14 minutes per mile. Elite marathon runners average under 5 minutes per mile.

What is a good 5K time for a beginner?

For a beginning runner, completing a 5K (3.1 miles) in under 40 minutes is a solid goal. Most recreational runners aim to complete a 5K in 25–35 minutes.
