Route & Travel Time Planning

Getting somewhere is only half the question — the other half is how long it will take. This collection estimates travel and hiking times. The Travel Time Calculator takes a distance and a speed and returns the duration, and can also solve the other direction: given a time budget, how far can you go. The Flight Time Calculator estimates how long a journey between two places takes by air from the great-circle distance and a typical cruising speed, which is handy for comparing a flight against driving. The Hiking Time Calculator estimates walking and hiking durations from distance and pace, and the collection also includes walking, hiking and driving time estimators for trip planning.

The math behind these tools is the straightforward relationship between distance, speed and time, applied to the mode of travel you choose. Change the speed and the duration updates immediately, so you can compare a relaxed pace against an ambitious one before you commit to a plan.

Two guides turn the numbers into real plans. The hiking time estimation guide explains Naismith's rule — the classic formula that adds time for ascent to the base walking pace — along with its modern refinements, and shows how to adjust estimates for fitness, pack weight, terrain and weather. The road trip planning guide walks through planning a longer journey from start to finish: choosing a route, breaking driving days into sensible legs, budgeting for fuel and stops, and what to check on the vehicle before leaving.

Use these calculators to sanity-check an itinerary, decide whether a day hike fits in daylight hours, compare travel options for a weekend trip, or plan the driving legs of a multi-day road journey. Parents planning a family drive can work out realistic daily distances so the trip stays enjoyable rather than exhausting. Cyclists can compare route options by seeing how a headwind-adjusted pace changes the day's riding time before choosing the flatter road.
