I have been tracking my runs with the Workout App, and the distance/pace/calorie calculations seem to be much different from those calculated by MapMyRun (and other distance tracking devices as well). The Workout app Will consistently underestimate the distance of my run (3.5 miles versus 4 miles respectively). I was curious to see if anyone else had the same problem. I have carried my iPhone with me on all my runs.

My question is how do you know that your other devices are the most accurate ones?

Great job in figuring this out! I ran today with the phone vertically, and the distances were very consistent. Let's hope a future patch solves this problem.
What's problematic with this is apps like RunKeeper give you an accurate GPS distance from the same iPhone that the Workout app uses to calculate distance.
I use Strava and the watch for cycling, the distances are reported the same.
Your issue has to be as a result of something else.
It has already been theorized in this thread and elsewhere that this mainly affects running. My walking distances have been spot on with the Workout app.
Agree, but I have never seen it described that it specifically uses the GPS to measure distance, only calibrate. So then maybe its my bad if it says that somewhere else.
