Race Pace Calculator

How to Use the Pace Calculator

1. Select whether your distance is in kilometres or miles
2. Enter your race distance
3. Enter your total time using hours and minutes
4. Instantly see your average pace per kilometre or per mile

This calculator is ideal for race planning, training sessions, or sense-checking a goal time before race day.

Why Race Pace Matters

Getting your pacing right can be the difference between:

• Finishing strong vs. blowing up late
• Running a controlled, confident race
• Hitting a PB without overcooking the first half

Many runners start too fast. Using a race pace calculator helps you set a realistic, repeatable pace that matches your ability and training.

When Should You Use a Pace Calculator?

A race pace calculator is useful if:

• You’ve set a target time and want to know the required pace
• You’re training and want to dial in race-specific sessions
• You’re unsure whether your goal is realistic
• You want a simple pacing reference on race week

Many runners use it in the final weeks before race day to lock in their plan.

Pace per KM vs Pace per Mile

In the UK, most races are measured in kilometres, but many runners still think in miles. This calculator allows you to:

• Switch between min/km and min/mile
• Understand how your pacing translates between units
• Avoid confusion when following training plans or race signage

Frequently Asked Questions

What is a good race pace?

A good race pace depends on your fitness, experience and distance. Shorter races allow for faster pacing, while longer races require a more conservative, sustainable pace.

Should I aim for even splits?

For most runners, even or slightly negative splits (running the second half a little faster) lead to better race results and a stronger finish.

Can I use this calculator for training?

Yes. Many runners use race pace calculators to set paces for tempo runs, intervals and race-specific workouts.

Does this work for beginners?

Absolutely. Whether you’re running your first 5K or training for a marathon, understanding pace helps you run more confidently and consistently.
