I hope I can explain what it is I am looking for.

I want an app that can can estimate how long it will take for me to complete a ride or run based on my current average speed.

Example.
I enter in the distance (62.5 miles) and press start.
Some time later I check the app and see I have gone 23 miles at an average speed of 14mph. Estimated time to complete 62.5 miles is...

Would be even better if it could tell me the time of day that I should complete the ride. This would help when friends and family want to meet you at the finish line of an event.

So far I have not been able to find anything quite like this. Yes I could do the math but I am lazy and hate math

Does anything like this exist and I have not found it yet? Some apps do so much it is hard to tell if they have this feature or not.
