Using Apple Watch to track treadmill runs is probably not a bad idea

I don't really like treadmills.  In fact, if running outside is a legitimate option, then I run outside. However, from time to time (like when one tosses one's spikes during a half marathon) it's best to just hop on the treadmill rather than risk an icy injury.

So this begs the question, how does one track a treadmill run?  Clearly you can just manually add the raw data from a run to apps like Runtastic, but did you know that the Apple Watch can track your treadmill run and somehow even provide a distance total for you at the end of the workout?  I didn't know this until I was on a treadmill a few days ago and noticed several distance alerts (1km, 2km etc.) which seemed a bit strange... for obvious reasons.  At any rate, the distance alerts and splits aligned with the data from the treadmill display.  Nice.

You can track a number of activities, from cycling to rowing and stair-stepping.

"No Goal" is probably a poor choice of words to use in describing a 7k workout, but since I'd prefer to retain the option of maybe going 7.25 or 7.5, I choose the "open" option.
