how do you get it to base off GAP zones?
Strava premium shows 'Pace Zone Analysis' which is actually GAP zones. When entering AP intensity manually you could base it off that. Eg. Time in 'Active Recovery' is zone 2 on AP, 'Endurance' zone 3, 'Tempo/Threshold' zone 4 and 'VO2 Max/Anaerobic' zone 5. To cross-check with Strava each time is easy but could become annoying and time consuming. Could perhaps be more useful in determining AP zones because it's consistent (assuming accurate vert) unlike HR however still doesn't account for surface technicality (which running power would) - eg. Orienteering might not be accurately reflected in intensity because pace is usually slower than straight up running despite similar intensity exerted. Make sense?
makes sense. i definately could not be bothered with that. :)
I'm just letting wrist-zones do their thing, accurate or not. I'm then moving time-in-intervals up to a 5. seems reasonable to me given TRIMP is a purely estimational thing anyway.
Also note - RPE is generally accepted by all the scientists in the podcast i've been listening to as the best way of doing any of this stuff. The AIS pretty much dump all peripheral data and rely on RPE surveys on their atheletes. If you really want it to be as accurate as possible, i'd use that... otherwise i think its all gonna be pretty useless unless you're a road/track runner
Yeah agreed. The only issue with RPE is you really have to judge it immediately afterwards otherwise time skews it. A degree of self-honesty is also required too.
BTW. Stravistix just upgraded their trend graph. they now use HR and power where its available, and where its not, use estimated cycling power and running speed vs functional threshold speed.
although its a long way from perfect... it has somehow caluclated tarawera as a stress score of 90... thats about the same as 2 hard cycling commutes haha
