#Stop SegCumul ClimbPace ElapsedETA BankWind Tuf? Toughness (0–10) — how hard each segment is, combining:
• Climbing (ft per mile)
• Headwind — counted as the climb it physically equals (≈12 ft/mi per mph), ×1.25 for the mental drain of a relentless headwind (≈15 ft/mi per mph applied)
• Temperature — 0 in a ~50–68°F comfort band; rising penalty in heat (the bigger effect) and a smaller one in cold 0–3 easy 3–5 moderate 5–7 hard 7+ brutal
