Relative Effort

How does it work?

Relative Effort, found on the activity details page, measures how much cardiovascular work went into any activity that has heart rate data or Perceived Exertion. A short and hard activity can require just as much effort as a long and leisurely one, and Relative Effort makes it so you can compare the two. Not only that, but different activity types are weighted so that your efforts can be compared across sports, and your values are personalized to your own heart rate zones so you can even compare with other athletes.

If you and a friend both ran your hardest 10K effort, your Relative Efforts would be similar even if your finishing times are different. Similarly, if you rode a bike as hard as you could for the same amount of time, your Relative Effort would be comparable.

Weekly Effort

Your Weekly Effort can be accessed from the activity details page or your profile page on the Strava mobile app or website. You can also easily compare your Weekly Effort and Fitness chart from the mobile app by selecting You > Progress.

The weekly Effort view shows your total Relative Effort for the week so far. It also indicates how you're trending week over week and provides a weekly Relative Effort range, shown by the white band in the middle of the graph. This area represents an estimation for an activity that allows you to maintain or build fitness while minimizing the risk of overtraining.

  • Within range: A productive amount of activity to maintain or improve your fitness. Weeks in this range are not likely to require additional recovery time.


  • Below range: Lighter than your average amount of activity. Aim for levels below your weekly range when taking a recovery week.


  • Above range: Higher than your average amount of activity. This may signal that you are increasing your efforts too quickly and potentially increasing your risk of injury or overtraining.



How can I make sure my weekly range is accurate?

Your weekly range becomes more accurate the more your uploads represent your normal activity level. Keep on recording!

Why can't I see Relative Effort for my activity? 

Relative Effort is only available for subscribers on activities that contain heart rate data or have a Perceived Exertion entered. If your activity does have heart rate, and you don't see it on Strava, check that you've allowed Strava to access health-related data.
