Race Planner: Set Your Target Pace and Speed

Measuring the pace of a race

Prepare for your race with the right pace and speed


Do you have a time goal for your next race, but you don't know what pace to use to achieve it? Our race planner makes it easy to determine:

✔ Target pace in min/km to maintain a steady pace
✔ The corresponding speed in km/h to better visualize your effort
✔ Pace markers for different race distances

With this tool, you will be able to structure your training and adjust your pace optimally to achieve your goal.

Why Use a Race Planner?


Setting a goal is one thing; knowing how to achieve it is another. Proper preparation requires careful management of your running speed.

Example :
• Are you aiming for 1 hour 45 minutes for a half marathon (21.1 km)? The tool tells you that you should run at 5:00 minutes per km or 12 km/h.
• Are you training for a 3h30 marathon? Your target pace will be 4'58''/km or approximately 12.1 km/h.

Whether you're running a 5K, a half marathon, or a marathon, knowing your pace helps you prepare better.

How does the Race Planner work?


Our tool is very easy to use:

Enter your race distance (5k, 10k, half marathon, marathon or custom distance).
Enter your time goal (e.g. 40 min for 10 km, 1h30 for half marathon, etc.).
Click on “Calculate” and immediately get:
• Your target pace in min/km
• Your target speed in km/h

Example of use:
• You run a marathon in 3h45 ➝ The tool indicates a pace of 5'20''/km and a speed of 11.3 km/h.
• You want to run 10 km in 50 minutes ➝ The tool gives you a pace of 5'00''/km and a speed of 12 km/h.

This will help you adjust your training sessions and avoid going too fast or too slow on race day.

This chart allows you to identify at a glance your target pace based on your distance and goal.

How to Use this Data to Optimize Yourself?


Once you have determined your speed and pace, it is crucial to adapt your training accordingly:

Work on your endurance by running slightly below your target pace.
Perform interval training sessions to improve your ability to maintain your target pace.
Simulate your racing pace during your long runs.

A good training plan relies on intelligent pace management. This tool will help you calibrate your effort so you don't explode at the end of the race.

Race Pace Planning FAQ


1. Why is it important to know your target pace?


Your target pace is your primary guide to structuring your training and optimizing your race performance. Poor pace management can lead to premature fatigue or a disappointing time.

2. How to use this calculation for training?


Depending on your target pace, you can calibrate your interval, threshold, and long-distance sessions to get your body used to keeping up.

3. Is this valid for all distances?


Yes, this tool is suitable for races ranging from 5K to ultramarathon. You can also use it to prepare for a triathlon or a mountain race.

4. Can I use this tool for trail running?


The tool provides an estimate that is valid for flat terrain. In trail running, pace is strongly influenced by elevation and terrain.

While this tool allows you to set your target pace based on a goal, you can also use our race time simulator to estimate how long you will take over a given distance based on your past performances.

With this race planner, you now have a clear strategy for achieving your time goals in competition. Test it and adapt your training to improve consistency and performance!
