Garmin ENDURANCE SCORE & ACTIVITY IMPACT

Must Read: Garmin Fenix 7 PRO Review & Where to buy

Source: @JW many thanks

Garmin is set to add two new endurance-related metrics for endurance athletes to the Fenix 7 PRO and Epix 2 PRO. These will come to all endurance athletes, including cyclists, runners and swimmers. Initially, it will definitely be available on Garmin Connect, but perhaps also with components on Forerunner and Fenix watches.

Q: What is endurance Score

A: Endurance score is an indication of your general ability to sustain physical activity for an extended period

Q: What is activity impact

A: This is the effect of specific workouts on your endurance ability

all the details – new Garmin Fenix ​​7 Pro, new Elevate, new features, new Epix Pro

How Endurance Score (ability) Works

Simply track your activities as normal for two weeks using a compatible Garmin watch. All activities contribute to the score, but longer aerobic activities in any sport will have the biggest impact. The more completed activities you add to the score, the more accurate it becomes.

While any activity from any sport will count, the top three most impactful sports will be more influential… perfect for triathletes! Garmin sensibly adds caveats suggesting that if you cycle a lot, you should not necessarily expect the endurance you gain there to fully transfer to your running endurance.

We don’t know the details of the algorithm; however, it is known to be multi-factorial, taking into account, to varying degrees and where available, the following: activity duration, activity intensity, speed, power, VO2 max, age, gender, BMI, and activity level.

Developing and reinforcing your endurance base takes time and regular, consistent effort. The peak benefits of endurance training, however, can be lost during a relatively short period of inactivity or by doing fewer endurance-building activities. As a result, both long- and short-term training perspectives are factored into your endurance score calculation to reliably reflect your current estimate.

How Endurance Score is Displayed

Most (if not all) feedback will initially be in Garmin Connect. Your endurance score will be set against a 4-week baseline and contextualised to your age and sex. There will also be more dynamic content and textual feedback explaining how to maintain or improve your endurance in the future.

Takeout

This new feature set looks promising for endurance athletes. It was probably developed beyond a simple metric into what seems to be a richer, deeper feature, given the relative success of the stamina metric. While the stamina metric is pretty good at pacing you during an individual workout, the new Endurance Score addresses broader issues related to your overall endurance and training progress.
