There is already a virtual training partner. There are two Values which can be displayed for this: "Dist fr Competitor" and "Virtual Lead".
The current version seems to have a bug so the competitor is not displayed correctly on the map. The next version should fix this problem (this worked already in an older version).
It Would Be great if you can add a visual virtual partner on the screen so that we can be able to see how good we are doing comparing to the partner based on the speed, by showing the time and distance comparing to the virtual partner.
