A random group of internet folks (including myself) found Endurance Score on our Garmin watches. We figured that it could be interesting and started to monitor to try to understand what it does, how it “thinks” about life and the bigger picture and ultimately to use it to make fun of each other.

As science seems to be ignoring this important topic

the following summarizes our findings of our carful data evaluation.

Note 1: data were recored on 2x Enduro 3, 1x Enduro 2 (the expensive one) and 1x Fenix 7X (which randomly restarts every 20 km which takes around 2 min). The E-Scores of us are between 7500 and 8500
Note 2: all of the below is 100% true
Note 3: we have a reference group (2x Enduro 3) with E-Scores of around 9500 and they are better runner without a doubt. So the score works.

There you go:

1. The E-Score takes a random amount of points from you every day. Probably to remind you that the word endurance originates from the verb “to grind“. Its a circle, not an arc!
2. Once you start to focus on the E-Score it will rise for a certain amount of time. (To give you some initial reward)
3. Soon after the E-Score will plateau around a number specific to you. Factors influencing this number comprise but are not limited to the following:
   1. the weather forecast at your location
   2. the amount of push-ups you do before going to bed
   3. your BMI
   4. the color of your eyes
   5. the amount of running shoes you have
   6. your favorite soccer club
   7. the number of pets you have
   8. whether or not your tinder profile is up-to-date
   9. the number of followers on your LinkedIn profile
   10. wether or not you wear pants while working
4. The E-score acknowledges if you follow a structured Garmin training plan: if you do all those stupid threshold, VO2, recovery and long-runs and score all of them at 100% training fulfillment you may not lose points. If you however score 99% or less on one of them you have a problem.
5. It seems that you gain some extra points if you open the daily push message on your watch from Garmin on X within the first 10 seconds while training. Nasty little insights into the rabbit whole. Garmin usually twitters between 7 and 8 p.m. CET.
6. The internet says the E-score acknowledges long runs. That is part of the truth. If you do them in min 50% HR zone 3 it may be true – if you stay below that you lose points no matter of the distance.
7. The E-score acknowledges the olympic distance (100 mile +) with a fixed amount of around 200 points straight away.
   1. If that activity took you more than 24h and if it was an easy course the E-score is reduced by 100 points straight after the first sleep after the run. It feels like winning the lottery with the numbers from last week.
8. If you end up with a double digit recovery time after a run – don’t even try to run. Try to lower your recovery time. To do so any recorded activity (the longer and the more often the better) EXCEPT running will help. The following list of activities is sorted starting with the most beneficial impact on recovery time reduction. If the activity type is not on the first page in your list you may as apply the suggested type given in (brackets):
   • Doing the dishes (Cardio), reading a book (Cardio), declare your taxes (Weight Lifting), Pickle Ball, Wingsuite, Sex (Rope Jumping), Chess (Deep Breathing), Yoga, Pilates, doing SOME drugs (Apnea Diving), Mountaineering, Fishing, Hunting, Indoor Rowing, MMA, Lacrosse, Cycling and Swimming.
9. The only thing to ultimately boost your E-Score is daily (better 2-3 times a day) training between 15-300 km at HR zones 3-5. We have data to support this (not ours of course).

Hope that helps!
