Bikepacking Route Planner Calculator — Days, Calories & Water

Plan your bikepacking route with realistic day estimates, calorie needs and water requirements based on distance, elevation and terrain.

How We Calculate This

Riding Days

Riding days are calculated from the adjusted effective daily kilometres, which accounts for the climbing penalty based on elevation per day and terrain type. Total distance is divided by this effective daily distance.

Time per Day

Estimated hours per day starts from distance ÷ terrain-adjusted average speed (which already bakes in slow climbing across the whole route) and adds a partial climbing allowance using a modified Naismith's Rule: 10 minutes per 100 m of ascent, scaled for terrain, of which half is added so concentrated climbs are not double-counted.

Calories per Day

Calories use the MET formula: calories/min = MET × body weight (kg) × 3.5 ÷ 200, multiplied by daily riding minutes. The 3.5 mL O₂/kg/min constant is defined per kilogram of body mass, so only your body weight goes in the per-kg term. The carried load is reflected by a modest uplift to the MET value (half the load-to-rider weight ratio) rather than by adding load mass into the formula. Base MET values range from 8 (road) to 10 (singletrack), with mixed terrain at 8.5 (Compendium of Physical Activities, "bicycling, mountain, general").

Water per Day

Water is estimated as a base 2 litres plus 0.5 litres per riding hour plus 0.3 litres per 500 m of climbing. Adjust upward for hot or high-altitude conditions.
