I’ve been using the W’bal chart on my rides and it seems to be pretty accurate in terms of when I dig deep and empty the tank.
What I’m less sure about is the replenishment rate? How is that calculated? Surely it will be different for everyone? Is there a way to “personalise” it? e.g. We all know younger people seem to “recover” more quickly from intense efforts.
Just interested to know. I couldn’t find anything about it.
Slightly related question… I took my CP and W’ parameters from the intervals.icu estimates but they are clearly wrong because my W’Bal repeatedly goes negative even though I am no where near my limit. Is there a way for intervals.icu to automatically update its estimates when the W’Bal goes negative?
on a ride which you see the -ve value, then it’s time to change your W’ number. Either in the /SETTINGS page or within the specific activity (and it will carry forward for future)
I’ve found the w’bal from zwiftracing.app to be pretty close, but I suppose it does depend on the data it gets fed from your racing results. (All this assumes Zwift and Zwift racing though).
