I would recommend a site like CalTopo (my favorite) or Hillmap; you can import GPX files into them, or click on points to define a path. For Caltopo, creating a path by clicking might not be immediately obvious; first choose "Add New Object", then select "Line", and once you've edited any details you can click each waypoint or hold down shift while ...

In terms of planning distances I figure 5:1 for elevation. That is, a meter up effectively adds 5 meters horizontally. This is true for up and down both. In practice the up part takes longer for any but the most fit, but coming down is still slower than flat (you are picking your foot landing more carefully.) Both going up and going down you are taking ...

So if we'd walked, say 10Km as the "crow flies" and climbed 1Km how far had we actually walked (roughly)? (looks like Math Markup isn't enabled here?) km = sqrt( distance^2 + elevation^2 ) = sqrt( 10^2 + 1^2 ) You added a whole 50 meters to your hike with that 1km elevation gain. That's assuming a steady slope. If the route is up hill and down ...

What exactly do you want to measure? If you want to estimate shoe usage, it would be better to measure steps, not the distance. If you want to estimate fatigue, than there's a heuristic, you should assume that 100m up is the equivalent of 1km on flat terrain. So you have walked 20 km equivalents. It has taken you twice as much time as you would be ...

You can get a good estimate of the distance walked by timing or pacing. Naismith's Rule (a way of estimating the time to walk a distance when ascents are involved) can help with the timing aspect but is only an estimation of the time taken to walk a certain distance taking ups and down into account. From the knowledge of expected average speed and time ...

Pythagoras is actually exactly what you would use, approximated as finely as you need for accuracy. What I mean by approximated, is: If you are following a continuous incline, you really only need one right angled triangle to calculate your hypotenuse, but if your incline varies, a more accurate figure will be gained by taking each change of incline as a ...

Bing maps supports topo-maps (in the UK at least and not on the mobile client) via the ordanace survey

In places where the contour lines are closer together, the slope is steeper. Where the lines are further apart, the slope is gentler. In a spot where you see several lines merge together, that is a sheer drop-off. Avoid those, obviously. Look for nesting Vs on the map. These are ridges, or possibly ravines. Water (blue) bisecting the V will tell you it is a ...
