Hike planner: time, water, calories, weather & daylight
Enter the distance and climb of your hike, or pick a stage of a long-distance trail. The planner estimates how long it will take, how hard it is, how much water to carry and how many calories you will burn. Add a start point and a date to see the forecast and the hours of daylight.

How it’s calculated
Walking time
time = distance ÷ 4 km/h + ascent ÷ 600 m per hour
Difficulty
effort = distance (km) + ascent (m) ÷ 100
Water
water = 0.5 L × walking hours (× 1.5 hot, × 0.8 cool) + 0.25 L per 500 m ascent
Calories
kcal = VO₂ (ACSM walking equation) × (body weight + pack) × minutes ÷ 1,000 × 5
Weather
high point temperature = forecast − 6.5 °C per 1,000 m above the forecast point
Daylight
latest start = sunset − time with breaks − 1 hour
Frequently asked questions
Is the hike planner free?
Yes. There is no sign-up, and the calculations run in your browser. To show the forecast, the start point is sent through Outest’s server to MET Norway, the Norwegian weather service.
Which trails can I pick?
Every stage of the Lycian Way, the St Paul Trail and the Tour du Mont Blanc. For any other route, type in the distance and climb, and add a start point for the weather and daylight.
Can I share a plan?
Yes. Your inputs are kept in the page address, so you can copy the link and send it. Anyone who opens it sees the same plan. A trail stage link looks like outestapp.com/tools/?trail=tour-du-mont-blanc&stage=3.
How accurate are the results?
They are planning estimates based on simple rules of thumb. Your own pace, the terrain and the weather on the day will differ. Use them to plan, then adjust to what you find on the trail.
