📖 How to use the running pace chart

Why should you know your running pace?

Running pace, measured in minutes per kilometer (min/km), is a key metric for every runner. It helps you pace your effort, avoid starting out too fast, and stick to your goal right up to the finish line.

How to determine your target pace?

  • For a 10K: aim for a pace you can sustain while breathing in a controlled yet steady rhythm
  • For a half-marathon: start out 10-15 seconds/km slower than your 10K pace
  • For a marathon: aim for a pace 20-30 seconds/km slower than your half-marathon pace
  • For an ultra-trail: adjust your pace according to elevation gain and terrain conditions

Tips for a successful race

  • Test your target pace during your long training runs
  • Memorize your split times at key checkpoints (5 km, 10 km, halfway mark)
  • Start slightly below your target pace to manage the race-day excitement
  • Adjust as needed based on how you feel and the weather conditions
  • Save some energy for the final kilometers

Key running distances

This chart covers all major distances: from the 5K (the ideal distance for beginners) to the 10K (the most popular format), all the way through the half-marathon (21.1 km), the legendary marathon (42.195 km), and ultra-distance races up to 100K.
