# Can I run my steady endurance sessions based on heart rate? If so, at what percentage of my maximum heart rate?

With an up-to-date reference time, Campus' steady endurance pace should naturally take you slightly above your easy endurance zone in terms of muscular effort and heart rate. You can run based on heart rate — around 80% of your maximum heart rate — as long as you're using a reliable heart rate monitor, like a chest strap. Alternatively, you can run by pace, which should roughly correspond to the same intensity.
