Hikes
On foot, at your own pace.
A pedestrian profile, three paces, adjustable breaks and a grade that separates effort, technicality and risk.

A real pedestrian calculation
A loop or a point-to-point route on trails and footpaths, more technical trails only when allowed, maximum gradient and climb respected.
An honest walking time
Slow, average or brisk pace, heavy pack and personal setting: the time combines distance and elevation, and breaks are added separately.
The Vistavel grade
Effort is calculated, technicality and risk are declared: the overall level runs from green to black, and missing data stays unknown.

Your questions
Is the displayed time guaranteed?
No. It is an estimate based on the route, the available elevations and your settings. If terrain data is missing, the result shows a minimum time and an incomplete grade.
Can I use my own GPX track?
Yes. An imported track keeps exactly its geometry; changing pace or breaks only recalculates times and the grade.
