Tue 16 Dec (cont.): On to the park. Just the cooldown 5th lap (which were done really leisurely, as was 1) kinda tuckered out genuinely , and 2) trying to figure out how to access stored laps on my Casio watch... which can store 60 laps but no idea what key combos scroll thru recorded ones )... was divine, as proved in a gentle way, I were literally pushing the knee to its sane & construction boundary. Haven't done much exerting since my running days ended due to this same knee issue (in both knees at the time) in 2023... so not surprised rocking up to the park trail, was gonna be more sightseeing than exercise... Huh -- so since most of the SE entrance trail is 100m of downhill... felt the knee protest from the usual cooling down in the car... but that faded after the level lap of the football field... and felt just as good if not better, climbing the steep 1st big hill, and down the long drop other side, to the stream bed and lowest elevation of the lot. That downhill portion's been near-constant airteeth for weeks, readers -- had never felt the knee sturdy / solid enough, to handle this part of the trail gracefully, not for months anyway. Sure at the end transitioning back to climbing was a bit gimpy... but once climbing, went back to feeling good. Again, huh Even the final climb up the 20% hill... felt more strain than the climb out the streambed... but nothing like trotting atop the structure. This was very, very good... So wow -- guess I need to get 6 hrs sleep and eat just what I'd been eating last night... to get this knee into the fast swimlane
