Trail Suffer Score™

Measure Every Hike. Know What to Expect.

Objective trail difficulty based on elevation gain, steepness, altitude, distance, and technical challenge — built to compare hikes more honestly than vague labels like “moderate.”

Search a Trail

Find hikes, peaks, and classic routes by name, park, or region.

Check the Score

See total Trail Suffer Score, score band, and the factors that drive it.

Plan & Prepare

Use the breakdown to understand whether the challenge is steepness, altitude, or fatigue.

Top Trails

Start with benchmark hikes people actually debate — from easy day hikes to huge alpine days.

How the Score Breaks Down

This is where TrailMetrics becomes useful: not just a single number, but why a trail feels hard.

Difficulty Comparison

Longer days, altitude, and steep sections stack differently depending on the route.

What Makes a Trail Hard?

TrailMetrics separates different types of suffering instead of hiding everything behind one vague label.

Steepness

Sustained grades and sharp crux pitches drive lung and leg strain.

Altitude

Thin air reduces capacity and makes similar effort feel much harder.

Distance

Long approaches and long exits increase time-on-feet and drain endurance.

Terrain

Loose rock, talus, snow, and rough footing reduce efficiency and confidence.

Fatigue

Big days combine intensity, endurance, and descent damage into total cost.
