Hey all, I am new to the boards here. I have been running for about 2 years and am training for a half marathon. I have been using the Runtastic app on my iPhone 4 for the past several months. My husband wants to get me a Garmin 405CX for Christmas, but I’m not sure it will be any better than the iPhone app. Which is better, iPhone GPS app or Garmin 405CX? I would really appreciate your useful opinion regarding this. Thanks.
