This was an excellent long run to close the week: 13.8 km in about 1h40, with easy effort, normal legs, and comfortable sensations throughout.
The session did exactly what it needed to do after Thursday intervals and Saturday hill intervals: add aerobic volume without becoming another workout. Heart rate stayed controlled and the run felt like a relaxed tour through Palermo.
The small slowdown later in the run is not a concern, especially with some elevation and the need to hold back the urge to stop. The important signal is that the legs and effort stayed good.
Takeaway. The long run confirmed that the week was absorbed well. Keep using the long runs as aerobic consolidation, not as pace validation, especially when they come after quality work.
Next step. W03D2 Intervals. Threshold interval session with a small volume increase. Keep the first reps controlled and avoid turning the workout into a race.
