What this means

Full day hike — early start recommended

Plan to be on trail by 8am to finish in daylight. Bring 2 litres of water minimum, a full meal, and a headtorch in case you run late.

Earliest safe start to finish before dark: a 7am start puts you back at 11:21am.

All three models adjusted for your fitness, group, and conditions. Book Time weighted 50% in the final estimate.

Stay hydrated on the trail

For a hike this length, aim for 0.5L per hour of moving time. A reservoir pack keeps water accessible without stopping.

Methodology: Moving time calculated as a weighted average of Naismith's Rule (1892), Tobler's hiking function (1993), and Book Time — each weighted 25%, 25%, and 50% respectively. Adjusted by fitness, group, and condition multipliers. Energy Miles use the Greenman formula (1 equivalent mile per 2,000 ft gain). Shenandoah difficulty = √(elevFt × 2 × distMi).

How to use the hiking time calculator

Enter your trail distance and elevation gain for an instant estimate. The calculator runs three models at once and shows you a realistic range. Open Advanced Options to add elevation loss, rest breaks, group size, and trail conditions.

What affects hiking time

Elevation gain

Distance is almost irrelevant without knowing your elevation profile. Most hikers slow to 1-2km per hour on steep climbs regardless of their flat pace. The three models this calculator uses all weight elevation heavily, and rightly so.

Group size

Solo hikers move faster than groups, consistently. A group of six takes 15-25% longer than a solo hiker on the same trail. If you're leading a group, always plan to the pace of the slowest person.

Trail conditions

Wet or muddy trails add 15-30% to your time. Snow can cut your pace in half. If conditions are uncertain, use the Advanced Options to apply a conditions multiplier before you commit to a start time.

Rest stops

Most hikers massively underestimate their rest time. Photos, snacks, navigation checks, and regrouping all add up. 30 minutes is a realistic minimum for a half-day hike. Factor it in before you leave.
