Download the App
Tell your family and friends to download the app so they can track you. It's an easy way for them to figure out what time you'll reach each mile so they can watch. Even if your squad is cheering from home, it's a great way for them to see how you're doing.
I brought my phone and took a lot of pictures during the race - the experience of being a part of such a big race is incredible and the crowds are amazing.
