This was a good recovery run because it stayed true to its job. The legs felt heavy, the ground was wet, and the air was humid, but the run remained controlled from start to finish and never drifted into unnecessary moderate work.
The most encouraging part is the cost profile. Average heart rate stayed low for you, pace stayed relaxed, and the four short strides added a light sharpening touch without changing the character of the session. That is exactly what you want a few days after a substantial split long run.
The caution is simply that the heaviness was real. This was not a day to force rhythm or prove freshness. The value of the run is that it absorbed the previous load and reopened the legs a little, which now makes a controlled quality session the logical next step.
Takeaway. Good absorption signal. The recovery run stayed honest, the strides were enough, and the next move can now be a controlled quality session rather than another easy day.
Next step. Tempo Session. Make the next run a controlled tempo session rather than a maximal one. The aim is to spend time at a strong but sustainable effort.
