You can add comments anywhere in your workout using a hash (#).
Everything from the # to the end of the line is ignored when the workout is sent to your watch, so comments are useful for reminders, conversions, context, or little notes to your future self.
A line that starts with # is just a comment:
# Tuesday's tempo session
Warmup 10 min Easy
4 x 3 min Threshold, 2 min Easy
Cooldown 10 min Easy
Add a comment after any step:
500m 3:30–3:40/km # This might hurt!
5km 12-18mph # about 19-28 km/h
If the first line of the workout is a comment, Workout Writer uses it as the subtitle on the main workout list:
# Race week — keep it easy
Warmup 2km Easy
5km @ 5:30/km
Cooldown 1km Easy
