Forecast-derived garage estimate 78–82°F: sunny late morning, expect drift warmer during 55 min Today is longer but not harder: rest yesterday + good sleep supports volume; heat means no 5–6% incline challenge If actual garage is ≥82°F or stuffy: skip the Finish, stay 2.5–2.6/0–1%, cool at 45 min If HR >123 sustained: drop incline 1%; if >128, go 1.5 mph flat / stop If HR <112 at min 30 and garage <80°F: one small notch only (+0.1 mph or +1% incline) Drink water in small sips; ignore one bottle-raise HR spike if it settles quickly.
