CoachFrom the Coach guide
If you need to skip a run, keep these.
The runs that matter most in your week.
What a key run is
A key run gives the most to your training this week. Coach marks up to 2 runs each week.
How Coach chooses
A race or a threshold test comes first. In that week, it is the only key run. Then, for a half marathon or a marathon, the long run comes first. For a 5K or a 10K, the hard run comes first.
If you need to skip a run
Skip an easy run first. Coach does not add a missed easy run back. Before you skip a key run, move it. Open the run and select Move this run.
Not the same as
Standing commitment: a run you chose, such as a run club. Coach keeps it on its day. It is a key run only when it is a hard run.
Where this comes from
Coach gives priority to runs that prepare you for your race. This is a deliberate choice to help you decide what to keep.
