In running or riding, I'd like to see my ahead/behind time against a course that i have on my watch. It currently shows ETA, ETE, distance remaining, but i can't get the time ahead/behind compared with the timing of the course i've uploaded. So i'd like to race the course and understand how far ahead or behind time i am. I know virtual partner can do this as an average speed, but that's not very useful given it takes longer in hilly areas etc.
I tried racing an activity (not course) as well and it told me the ahead/behind at the completion of the activity but not during the activity.
