Selectable color coded route

Currently you can edit it with CSS: Maps on Connect.

I don't think this is what i'm looking for. I want the ability to colour code the route different colours based on speed, not simply change the colour of the route in totality. I've updated my post to suite

Then maybe applying a global hue on that colorful path?

@-moz-document domain(garmin.com)
{
 .leaflet-map-pane canvas { filter: hue-rotate(180deg); }
}

More options, like invert or sepia, are listed here: CSS filter Property.

Edit: ok, that different colors misled me, you probably mean to just add speed coloring option to activities' types which won't have it now. Then, as a workaround, you can change type of an activity to some type which supports speed, view a map, then change it back.

Yes it's the speed coloring option. I understand that the activity can be changed and then changed back but i feel that the amount of work required to just add an option/toggle to all the activities shouldn't be too much work. 

I agree entirely with Andreas Kaestel, even two years later. We should have the opportunity of colour-coded speed tracks in all activities, not just MTB. Garmin, please add that option for all activities.
