iPhone gps map draw
<p>i am developing a iphone app which will be used by marathon runners.
in that application which is based on GPS i need to draw the running path(something like a line) on the map based on start and stop point of the runner's GPS locations.
I am pretty new to app development, would be great if any of you can guide me on this or help with some code.</p>

<p>Thanks</p>
