I found out that Garmin LiveTrack and PacePro don’t go well together. It seems to cause PacePro to loose its ahead/behind information, which is annoying during a race.

This is about the mode in which you have LiveTrack automatically started from your watch (Garmin Fenix). Activating LiveTrack via your phone after you’ve started seems to work better.

In Intervals.ICU, you can select different power zones for running and cycling. I was interested in finding the appropriate power zones for running.

The power zones for cycling are less suited for running — for example, for a Z2 HR run, a corresponding cycling power zone is likely to be biased upwards. Physiological differences between cycling and running play an important role.

The following two figures show the difference where the running power zones are shifted to the right. (FTP in these examples is 380.)

And in this chart you see a comparison of the running-specific power zones available by default in Intervals.ICU (for an example FTP of 380):

Of course, Intervals.ICU allows you to setup custom power zones if needed.
