Elevation gain is the total amount a hike climbs uphill, measured in feet or metres, summed across every ascent on the route. It’s a key measure of a hike’s difficulty — often more telling than distance — since a short trail with big elevation gain can be far harder than a long, flat one.
Why it matters
Climbing is far more strenuous than flat walking, so gain (plus terrain) gauges difficulty better than mileage. Trail builders use switchbacks to spread it out.
Cumulative, not net
Every up counts, so rolling trails to a summit can total far more than the start-to-top difference. Trail runners call it vert.
Frequently asked questions
What is elevation gain?
Elevation gain is the sum of all the uphill climbing on a route, not just the difference between the start and the high point. If a trail goes up and down repeatedly, every climb adds to the total, which is why rolling trails can have surprising gain.
Why does elevation gain matter more than distance?
Because climbing is far more strenuous than walking on the flat. A 5-mile hike with 3,000 feet of gain is much harder than a 10-mile flat walk. Experienced hikers judge difficulty by gain and terrain as much as by mileage.
What's a lot of elevation gain?
It's relative to distance, but as a rough guide, over about 1,000 feet of gain per mile is steep and strenuous. Big mountain day hikes often involve 3,000-5,000 feet of total gain, which is a serious effort for most hikers.
