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.

Trip details
What it considers

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.
