Hiking Time Calculator

Estimate how long a route will take from its distance and its elevation profile, adjusted for your pace, the terrain underfoot and the weight on your back. The page returns a moving time, a breakdown of where the hours go, and rough figures for water and energy.

Distance, Climb and the Cost of the Descent

The estimate follows the classic walking-rule approach: a flat rate for distance, an added penalty for climbing, and a credit for descending. It then layers on personal and environmental adjustments and finishes with a break allowance and a safety buffer, so the figure is closer to a realistic day than a pure walking speed would suggest.

• The flat component uses a base speed of five kilometres per hour, so ten kilometres contributes two hours before any elevation is considered.
• Climbing is charged at one hour per six hundred metres of ascent, so a five-hundred-metre climb adds about fifty minutes.
• Descent is credited at one hour per nine hundred metres of descent, and it is subtracted from the total rather than added. It only applies when a descent figure is entered; the default is zero.
• A fitness multiplier scales the whole moving time: slow and beginner stretches it by thirty percent, average leaves it unchanged, fit trims it by twenty, and elite trims it by forty.
• A terrain multiplier stretches it again — no change on a good trail, twenty percent added on rough ground, and fifty percent added off-trail or bushwhacking.
• Pack weight only bites above fifteen kilograms, and each kilogram over that adds one percent to the time, so a heavy load is a gradual penalty rather than a cliff edge.

Getting a Day Estimate

1. Enter the route Distance in kilometres. This is the largest single input for most walks.
2. Enter the Elevation gain in metres — the total climbing, not the net height difference. Use a route profile or a guidebook figure if you have one.
3. Enter the Elevation loss if the route descends significantly. Because descent is subtracted, a big drop will pull the estimate down; leave it at zero for a flat or out-and-back route you would rather keep conservative.
4. Set the Pack weight in kilograms. Below fifteen kilograms it makes no difference; above that it starts to lengthen the estimate.
5. Choose your Fitness level and the Terrain type. These two multipliers move the estimate more than most people expect, so pick honestly rather than optimistically.
6. Press Calculate Hiking Time and read the result. The headline gives hours and minutes, and the table beneath shows the base, ascent and descent components, the two multipliers and the break allowance.

The Default Route, Traced Through

The page opens with ten kilometres, five hundred metres of ascent, no descent, a ten-kilogram pack, average fitness and a good trail. Walking through the arithmetic shows how each stage of the calculation shapes the answer.

• Distance contributes two hours, shown in the table as a base time of two point zero hours.
• The five-hundred-metre climb at one hour per six hundred metres adds about zero point eight hours, printed as an ascent contribution of plus zero point eight.
• With no descent entered, the descent line reads minus zero point zero hours and changes nothing.
• Average fitness applies a multiplier of one and a good trail applies a multiplier of one, so the moving time is unchanged. The table shows both modifiers as zero percent.
• The pack is ten kilograms, below the fifteen-kilogram threshold, so no weight penalty is applied.
• The break allowance is five minutes for each complete hour of moving time. At two hours and change, that is ten minutes, which is added as a sixth of an hour.
• The running total of three hours lands below the four-hour mark, so no additional lunch stop is added. The safety buffer then multiplies everything by one point one, taking the final figure to three point three hours, which the page displays as three hours and eighteen minutes.
• The recommendations add two litres of water, from half a litre per hour rounded up, and about five hundred kilocalories, from fifty calories per kilometre at average fitness.

Approaches to Judging Route Time

Alternative	Notes
A flat speed rule	The simplest estimate — distance divided by a customary speed. It is quick but ignores climbing entirely, so it badly understates a steep route and slightly overstates a flat one. This page's base component is essentially this rule, before the elevation terms are layered on.
Ascent-inclusive rules	Adding an hour per fixed amount of climb, as this tool does at six hundred metres, is the classic refinement and handles hilly terrain far better than a flat speed. The trade-off is that it needs an accurate elevation gain figure, which is the input people most often get wrong.
Timing a known section	Once you have walked part of a route, your own split times become the most accurate predictor for the rest, because they fold in your real pace, the actual conditions and every stop. The calculated estimate is a starting hypothesis; observed splits should replace it as soon as you have them.
A conservative planning margin	Many walkers simply add a generous buffer to whatever they compute. This page builds one in with a ten percent uplift, but the right margin depends on how remote the route is, the weather window and the group. For a committing route, treat the output as a floor rather than a target.

Where the Estimate Can Drift

The tool is a planning aid built from a few fixed rates, and several real factors sit outside it. Knowing which ones matter most stops the number being taken as a promise.

• The rates are constants. Six hundred metres per hour of ascent and nine hundred per hour of descent are reasonable average figures, but individuals vary widely and steep or loose ground changes them a lot.
• The break allowance is mechanical — five minutes for each full hour — and does not know about the length of a stop, the size of the group or how often you actually pause. Long lunches, photo stops and navigation errors are not modelled beyond the fixed buffer.
• The final uplift of ten percent is a single blanket margin. It is not adjusted for how exposed or remote the route is, so for a serious mountain day it may be too small and for an easy valley walk it may be more than needed.
• Calorie and water figures are rough rules of thumb. Calories are estimated from distance and fitness alone, ignoring load, and water uses half a litre per hour, which will be short in heat or at altitude.
• Your last set of inputs is remembered on the device and refilled when you return, so you can pick up where you left off. Nothing is uploaded, and clearing site data removes the stored values.

Hiking Time Questions

Why does entering a descent make the estimate shorter?

Because descent is treated as a credit, not a cost. The calculation subtracts one hour for each nine hundred metres of descent from the running total. The reasoning is that the walking-rule base speed already assumes level ground, so a long drop gives some time back. Leave the descent field at zero if you would rather keep the estimate on the safe side.

How much difference does fitness level make?

A large one, applied to the whole moving time. Slow multiplies it by one point three, average by one, fit by zero point eight and elite by zero point six. Moving from average to fit on the default ten-kilometre route removes roughly twenty percent of the time before breaks and the buffer are added, which is why picking the honest setting matters more than fine-tuning the distance.

When does pack weight start to count?

Only above fifteen kilograms. Below that the weight is ignored entirely. Above it, each kilogram over fifteen adds one percent to the time, so a twenty-kilogram pack adds five percent. It is a gentle penalty meant to reflect the extra effort of a heavy load over a long day, not a dramatic one.

What is the final ten percent for?

It is a safety buffer applied to the finished time, after breaks and any lunch allowance. It exists to cover the small delays that accumulate on a real walk — a wrong turn, a slower section, a longer rest — so the headline figure is deliberately a little above the pure arithmetic. It is the last step in the calculation, so it scales whatever the earlier components produced.
