I am following Jeff's 5 training plan. During the activities (for instance a cadence drill), I get the normal audible signals. This is fine. I also get some other signals that are not clear to me. I cannot find a list of the signals it can give me during an activity.
I have figured out that one signals is probably the time and pace it takes me to cover a kilometer. I figured this out because I always get the signals at exactly the same spot. The other signal I get is a heart with a line beneath during a cadence drill. I think that sometimes the line is close to the heart and sometimes there is more space between but I am not sure because I am running when I briefly see it. Is my watch trying to tell me to run faster so my heart rate goes up?
Where can I find this information? As far as I can see it is not in the user manual.
