I use Trainingpeak workouts on my Garmin 830. I like to keep the alerts (5 beeps sound) for the 5 sec countdown to a new workout step, but I dont want the alerts (no visual and for sure no irritating sound) for being inside or outside the power zones. So, 2 questions:
1) Can I turn off the alerts for power zones without turning off the countdown alert to a next workout step
2) If not, can I use 10 sec power for power zone alerts instead of 3 sec power, since 3 sec is way too unstable to be used for power zones.
Many thanks for any advice.
