"As I mentioned above, I was little annoyed that I could only view two
measurements at the same time during a workout. Fortunately, I had full
power over which measurements the watch was showing. I ended up using
heart rate and current pace as my default, and settled for hitting the
¡°View¡± button whenever I wanted to see my time or total distance."
