In this graph demonstrating cardiac drift, pace remains relatively constant (blue) while the heart rate (red) continually increases.

What can you do about cardiac drift?

Don’t be a slave to your heart-rate monitor numbers. Rather, use your heart rate as a tool to help you learn your efforts and paces and as a guide to help get you started on the right track.

One way to accomplish this is to learn to use breathing rhythm as a way to intuitively assess your intensity. You won’t be perfect with this method at first, so wear the heart-rate monitor and use it the first 10-15 minutes of your run to get on track. Then, cover it up and practice running by feel. Look at the data only after you’re done running and compare your breathing rhythm and the effort you felt to the heart-rate numbers.

By understanding the underlying concepts behind heart-rate monitors and other training gadgets, you can learn to better listen to your body and apply these tools to help you train smarter in the long-term.
