Runners split their time into laps so one bad lap doesn’t hide in the total. Look at your week one day at a time.

A single number for a long effort hides everything useful. A total time gives you the result and nothing about where it came apart, while splits show the lap where you faded and the one where you were fine, which is the only material you can train on. The same goes for a week that felt bad. Specific days inside it did specific things.

Break the last seven days down and rate them honestly, one line each. Find the day that actually went wrong instead of condemning the whole week. Fix that one thing and leave the rest alone.
