Include slope difficulty in Isochrone calculation - is it possible?

Hello, I am trying to create Isochrones assuming walking travel time as cost. The problem is it doesn’t seem to account for slope inclination as a factor in walking speed. Is there any way to include this?

Hi Steffan.
I was just given an answer for a similar question : Steepness not affecting the duration of bicycle routes
There might be an interesting option for you in the app.config, if you are running your own ORS instance.

for bike this is potentially possible (though not with our public ORS servers).
For pedestrian, this functionality does not exist.
