Need calorie tracking DURING the activity

I am part of a challenge that involves burning 500 calories minimum per day per workout. Unfortunately, whether I am cycling or indoor rowing or running, I don't get a report of the amount of calories while I am in the midst of the activity. Only when I save the activity do I see the calories. This really bothers me when I stop a workout and I'm at 490 or 450 - had I known I would of jogged a little longer. Any advice on how I might see calories reported during a workout?

Thanks in advance.
