📖 Overview
Estimate how long a hike will take using Naismith's rule which adds time for elevation gain on top of flat distance.
The default is one hour per 5 km plus one hour per 600 m of ascent.
🧪 Example Scenarios
Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.
| Input | Base Case | Higher Pressure Case |
|---|---|---|
| Distance (km) | 10 | 11.5 |
| Elevation Gain (m) | 500 | 575 |
⚙️ How It Works
This calculator applies a direct math model based on the inputs above.
💡This calculator is scenario-based. Better input quality leads to better decision quality.
Quick Reference
| Input | Example Value |
|---|---|
| Distance (km) | 10 |
| Elevation Gain (m) | 500 |
When To Use This
- Use this tool when you need a fast decision during active planning or execution.
- Use this before committing money, time, or tradeoffs that are hard to reverse.
- Use this to compare options using the same assumptions across scenarios.
Edge Cases To Watch
- Results can be misleading if key inputs are missing, stale, or unrealistic.
- Very small or very large values may amplify rounding effects and interpretation risk.
- If assumptions change mid-decision, recalculate before acting.
Practical Tips
💡 Validate units before comparing scenarios.
💡 Run multiple values to understand sensitivity.
💡 Use outputs as estimates, not guarantees.
