The Effort Score is calculated using equivalent mountain load:
Equivalent Distance = Distance + (Elevation ÷ 100)
This score estimates terrain load only. Weather, terrain roughness, and pace also affect real effort.
In mountain hiking, vertical gain is the primary stress factor. Research and field experience show that every 100 meters of elevation adds effort comparable to approximately 1 kilometer of flat walking.
This calculator estimates equivalent mountain effort, not subjective difficulty. Your personal conditioning determines how demanding a hike feels.
If unsure about your readiness, begin with Level 1 and progress steadily.
