It would be really useful if the alert you get (on the watch face) as you complete each mile or kilometre could actually display something useful.
Currently as you complete each mile or km, it shows a 1 mile, however at mile 2 it displays the exact same, at mile 3 it displays "1 mile", at mile 4 it displays the same, at mile 5, you guessed it, 1 mile!
You have the data, surely it would be a simple update to make the alert useful, ie when you are running a marathon knowing that you are at mile 25 could be really helpful, rather than trying to mentally keep track, which is what you have to do currently.
