How to use your pace data
Knowing your pace helps you train smarter. If your goal is to run a 5K in 25 minutes, you need to maintain a pace of 5:00 min/km. Use this calculator to set realistic training targets and track your progress over time.
For beginners, a conversational pace (where you can speak in short sentences while running) is a reliable way to stay in an aerobic zone without overtraining.
