This was a strong 10K-oriented interval session. The fast blocks moved from controlled to sharp without turning chaotic, and the recoveries did their job well.
Heart rate climbed naturally through the repeats, but the session still reads as productive rather than forced. The best sign is that the workout felt correct and entertaining.
This is the kind of work that can support VO2max and high-end running economy, as long as the next run stays genuinely easy.
Takeaway. Keep the confidence from the fast blocks, but let the next run absorb the work.
Next step. Easy aerobic reset. Easy aerobic running to absorb the interval load. Keep it relaxed, steady, and clearly below workout effort.
