Best site / app for tracking distance

[sheeesh]

Hi,

Looking for your recommendations for tracking distance in running - website or, ideally, iphone app.

Thanks in advance

Mapmyrun works if your phone has gps.

Thank you. Will try that one

Do u mean working out distances in advance from home without actually running the distance? I have an iPhone app called geomeasure which does that- it's a little bumbly and awkward but is pretty accurate. Im a bit of an app collector if u need others?
