This was a good quality session because it finally gave you another real tempo stimulus without looking flat or hesitant. The first work block landed well: controlled, smooth, and right in the zone of strong but sustainable running rather than survival.
What changed the feel of the workout was the second block. It moved clearly faster than planned, especially late, so the session finished closer to a hard sustained effort than to a clean tempo progression. That does not remove the value, but it does shift the lesson toward pacing discipline.
The context matters here. Heat, 94% humidity, and naturally responsive heart rate all raised the physiological cost of the run, so part of the drift is understandable. Even so, the best follow-up is absorption: keep the next run truly easy and let this session count as the week's main quality signal.
Carry forward. Good tempo signal and good motivation, but the main lesson is still control. In tough conditions, staying inside the target matters more than proving extra speed late.
What followed. Easy Run. Keep the next run genuinely conversational from start to finish. No need to force pace, especially if the weather stays warm or humid. The goal is to absorb this tempo session, loosen the legs, and arrive fresh for the next long run. If you feel very smooth at the end, you can add 4 x 15 seconds relaxed strides with full recovery.
