Examples
Route distance (km): 12
Total ascent (m): 600
Assumed level-ground speed (km/h): 4
Assumed ascent rate (m/hour): 600
Planned breaks (minutes): 45
Limitations
- Nonnegative distance km,total ascent m,break minutes;positive flat speed km/h,ascent rate m/h. Time=distance/speed+ascent/ascentRate+breaks. Inputs are your assumptions,no default Naismith accuracy claim,descent/terrain/weather/fatigue assessment or route/safety guarantee.
- Scalar controls accept explicit finite decimal syntax;positive values normally1e-12–1e12,nonnegative0–1e12 unless a narrower range is stated. JSON numeric rows use finite IEEE754 values within their stated bounds. Derived counts above1billion and nonfinite results refuse. Combined input<=400000UTF8 bytes;complete JSON<=4MiB. All processing stays in your browser.
