Howdy! First of all: thank you for your excellent work on the project!
I have GraphHopper 2.0 running locally on my Ubuntu and I am using the isochrone API to create some accessibility areas around points. So I have been trying with walking and hiking, but the resulting isochrones seem to be very small. For example I have time_limit as 1800 (i.e. 30 minutes), but this results of areas which have a radius of roughly 400 meters). With 4 buckets and time limit of 1800 the biggest isochrone should be equivalent of 2 hours of walking, but those isochones seem to be roughly 2 kilometers.
If I check the web api, it should cover much bigger area (which seems more realistic):
So do I need to change the configs somehow or what am I doing wrong?
