This second segment confirms that the long run held together well after the watch failure. The pacing was remarkably steady for most of the file, with kilometre splits sitting in a tight range around 6:28 to 6:42 per kilometre, which is exactly what you want from the back half of a long run.
What makes this especially useful is the durability signal. This was not the fresh opening of a run; it was the continuation after an earlier segment, and the legs still stayed composed. That gives the whole day more value than a single file might suggest, because it shows you were able to resume the session and keep the effort under control rather than fading into survival mode.
The caution is cost. Heart rate stayed high from the start of this second part, which makes sense after the first segment and the messy setup of heavy food, some alcohol, and a split recording. The correct reading is that this was a successful endurance day with real load, so the next step should be absorption rather than another demanding workout.
Takeaway. Good durability signal and a successful completion of the split long run, but treat the day as one substantial endurance session and recover accordingly.
Next step. Recovery Run. Keep the next run very easy and very honest. The goal is to absorb the full cost of this split long run, loosen the legs.
