Fremont is sunny and ~65°F at 11am, ~70°F by noon; garage estimate 76–80°F with possible warm drift. Use actual thermometer if available.
Today is a Z2 reset: Thursday was very easy (42 min HR 86–113), but yesterday reached 127, so do not stack a second push day.
If actual garage ≥82°F, shorten to 20–30 min easy or skip. If sustained HR >125 for 2+ min, drop to 2.1–2.3 mph flat; hard stop at 128.
If HR <110 at min 25 and garage <78°F, you may nudge to 2.7/2% only while staying below 123.
STOP if dizzy, chest symptoms, unusual shortness of breath, feverish feeling, headache, vision changes, calf pain, or sore throat/chest symptoms return. Small sips; bottle-raise spikes can be PPG artifacts. Sit 2 min before standing.
