Color-code the Activity map based on speed, elevation change, or power output
Instead of a blue line to show the route covered, it would be cool to have a multi-colored line that could show speed, elevation, and power output gradients. For example, if speed was the category selected, blue would be a relatively slower pace and red would be a relatively faster pace based on the overall or average pace of the entire ride. If you selected the elevation category, you could see where the steepest climbs were on a route. This could eliminate need for a terrain map, as the color changes would show gradients. I understand this can all be seen on the computer. It would be neat for mobile.
