Hope someone can help me out, im struggling with the following problem.
I use a Garmin training plan (intermediate half marathon) together with my forerunner 410. The workouts are synched to the watch and all seems to be working fine except for the interval trainings.
Example of an interval workout description:
Run in Z4, threshold 3 minutes.
I assume this would mean: Run in HR zone 4 for 3 minutes.
But my watch will *beep* and warn me when I hit zone 4 and wants me to stay in zone 3.
Is this familiar to anyone?
