Simulator · Distance and climb into hours

Stage Simulator

Enter a stage’s distance, ascent and descent, the terrain, your pace and the weight on your back, and the simulator gives the hours, the calories and the water for the day, then splits a long route into stages that fit the daylight.

The classic rule says one hour per five kilometres plus one per 600 metres of ascent, and it is wrong for every surface except a good path with a light pack. This simulator starts from Naismith’s rule, corrects it for terrain, load, descent and altitude, and checks the result against the daylight for the place and month.

Simulators

One place, one month, one calendarJourney SimulatorChoose a place, a month, the days you have and how you travel. The simulator lays out a day-by-day timeline with temperatures, daylight, sleeping altitude, effort and cost, and flags the days where the model gets nervous. Open

What the month does to the placeClimate SimulatorHighs, lows and rain days for all twelve months of any place, with a feels-like line, a clothing verdict and a side-by-side comparison of up to three places for the month you can travel. Open

Sunrise, sunset and the polar casesDaylight SimulatorAny latitude, any date: sunrise, sunset, day length, civil twilight and the golden hours, drawn as an arc. It knows about the midnight sun and the polar night, and it shows how fast the day changes around your dates. Open

The Simulation Brief

One place, one simulator, one honest number. Every second Sunday.

No newsletter theatre. A short e-mail with the place we modelled, what the model said and what the ground said back.
