Why is the feelings not obvious change in slope when i use the run on earth app?
Some other users feed back about they always get incline/resistance = 0 originally, but after change different map routes, they feedback that found different incline/resistance values. Please try some other routes around the world.
For your information, the app get the data of altitude height from google map, then calculate the gradient to shows the incline/resistance when you sport, so the app automatically adjust the incline/resistance according to the slope of the route planning.
And sport movement distance of the length will affect feelings of the incline/slope.
