This was a strong long run and a good endurance signal. You covered almost 15 km at a steady rhythm, felt comfortable for most of it, and still had enough strength to include a faster late section.
The positive side is clear: after Thursday's sharp interval session, the legs still responded well and the pace stayed confident. That suggests your aerobic base and 10K readiness are both in a good place heading into Carrera Maya.
The caution is that the heart rate tells a heavier story than the perceived effort. This was not an easy long run internally, so the next session should absorb the load, restore freshness, and avoid adding more intensity too soon.
Takeaway. Strong endurance signal, but respect the hidden cardiovascular cost. The fitness is there, so the next move should be an easy recovery run that protects freshness before the final race week work.
Next step. Easy reset with light strides. A relaxed recovery run to absorb the long run and keep the legs loose. Stay easy throughout, with only a few short strides if everything feels smooth.
