Today I threw over to do some supplemental endurance work and loaded up Taku. Taku is a 30 minute workout categorized as an endurance workout (if you are not familiar with it). I only shifted the gears once and that was going from the first interval to the second, I resolved to do the workout single speed style.
In the third interval I noticed my cadence slowly but surely dropping while my power stayed steady (or so every slightly crept up). See the below Golden Cheetah trace with the upper trace being cadence and the lower trace being gear ratio. The power is more or less steady.
I have a conjecture as to what is going on. I believe my pedaling is becoming more efficient or perhaps more steady around the full pedal stroke. That is the application of force around the full pedal stroke is becoming more smooth as I focus on that. Is that a reasonable belief? Do you observe the same in your training and riding?
So, does that what was once a light spin eventually becomes mashing and using fast twitch muscle? It can be frustrating as sometime it might take me a while to find cozy gearing and then a few minutes later I look to see I’m “mashing”.
