Hike Fuel Calculator
Estimate your water, calorie, and electrolyte needs for any Sri Lankan trail. Tuned for tropical humidity, altitude shifts, and pack-weight load.
Built for Sri Lanka’s tropical conditions — humidity, sudden rain, and the steep climbs of the central highlands all change how much water and energy you actually need.
- Tropical humidity — adjusts hydration for high-humidity hikes
- Elevation gain — accounts for steep climbs like Adam’s Peak
- Pack weight — heavier pack = higher calorie burn
- Heat index — extra fluid loss above 20°C
- Altitude — higher MET cost above 1,000 m
Output is a planning estimate. On hot days or strenuous terrain, drink to thirst and top up at every water source.
