Understanding Different Training Paces

A long run calculator often provides various training paces based on your inputted data. Understanding these paces is essential for effective training:

  • Easy Pace: This is a comfortable, conversational pace where you can easily hold a conversation. It's perfect for building aerobic endurance.
