showing route taken during walk or run on map.

Hi,

I want user to be able to see the route he takes during walk or run on a map, while he is walking and after in history.

I have got the users location and loaded a map. From what i have read, i'lll have to continuously annotate the map with a marker while the user is walking or running. But I don't clearly understand the MapKit apis for annotation and annotation view. Can someone guide me how to go about it. I just need an overview.

Thanks
I have accuracy set to kCLLocationAccuracyBestForNavigation On and i tried out MKMarkerAnnotationView. I see markers very spaced out instead of a continous trail and they arent accurate either.

Note- my iPhone’s bluetooth is not working (since kCLLocationAccuracyBestForNavigation Also uses other sensors)
