I have come to the conclusion that i might have a problem.

I've been doing the vast majority of my training inside this year on Zwift. 75% of my rides have been workouts using ERG mode. (A few group rides typically for 50K+ rides and a few races.)

I am sneaking up on my A race (Miamiman Aquabike) and had planned to do a ride using power alarms on my watch and try to keep my power a bit under race pace.

I set my Garmin 920XT to alarm under 240W and over 280W

In the first 20 minutes of the ride i don't think i ever went more than 20 seconds without an alarm.

I increased the high range to 320W and i got to a couple of minutes without alarms.

Eventually, i just had to turn off the alarms and just ride.




My questions are:

1. Is it an unrealistic expectation that i should be able to ride within a 40W band? (I think the Garmin is alarming on about a 1-2 sec average .... so it fluctuates like mad)
2. If it am not looking at an unrealistic expectation, how do i fix this?


FWIW, i have tested with a Kickr as a power source and Favero Assioma pedals. (My LR balance is typically about 49%/51%, Torque effectiveness is 72%/72%, and smoothness is 19%/20%)

Thank you for any help

I do the same thing as them, just slower
