Running Stress Score

Running Stress Score is a metric that Stryd uses as a variant of the training stress score:

https://blog.stryd.com/2017/01/28/running-stress-score/

There are some questions on how to find a value of the K described there, like explained here:

http://www.georgeron.com/2017/08/an-equation-for-running-stress-score-rss.html

Allan Olesen mailed me about his search for K: "I couldn't find a value of K which would fit. It

wouldn't fit my own runs, and it wouldn't fit the examples in the table in the article.

So I started messing with the factor of 100 in the article and discovered that I could make everything

fit if I changed it to 108 instead. With this, combined with a value of K of 3.5, my own runs would fit,

and all examples from the table in the article would fit, except two.

Of the two table values which didn't match, one was probably a typo - a value of 0.65 repeated in

both columns. The other one was probably redacted on purpose because the article writer was hell-

bent on making the result fit with his assumption of 100 RSS/hour when P = CP - which will never be

possible if the assumed factor of 100 is in reality 108."

I have taken Allan's take on this, with his proposed formula:

RSS per sample = 108/3600 x sample duration in seconds x (Power/CP)^3.5

Power to heartrate ratio

Power to heartrate ratio (P/HR) = Power/ Heartrate (Watts divided by beats per minute)

An increase in value shows increased endurance, see

for some reading.

Training effect

Training effect is a metric developed by Firstbeat and licensed by Garmin. On this page you can find

Lap pace and structured workouts

Since the summer of 2018 lap pace and other lap related metrics are working for automated laps,

produced by a structured workout step (thanks to the CIQ3-firmware update by Garmin). At the end

of every workout step, Datarun premium resets the lap values it works with to display the metrics.

Unfortunately that's not the case for the FR735xt, as it hasn't received the update to CIQ 3 firmware.

Lap metrics aren't and won't ever be working for the FR735xt in a structured workout...

Power workouts

Currently in the standard Garmin structured workout option, it isn't possible to choose a power-

based workout for running. In copy version 1 I created a solution for the Fenix 5x and Fenix 5+

watches and I hope to create a "poor men's version" in copy version 3 for the FR735xt, FR935 and

Fenix 5[s] (and yes I also paid good money for my FR935 in 2019, but such is life ).

I am using 3 options:

1. a structured workout created in the normal "Garmin way". With this one can display the

desired power zone at the beginning of a new workout step and alert if the performance is

too low or too high.
