Now more than ever, this race must be run. Everyone, from the smallest child in the Kids Marathon to the oldest spectator on the course, must come together as one. We will show the world that simple human decency, empathy and compassion unite all mankind. Those who seek to do us harm will be brought to justice. Their cowardice and evil will only strengthen our resolve.
These are things that I and millions of Americans everywhere affirm as principles independent of any faith, race or creed. We won't give in to fear, ignorance, superstition and bigotry. We will run harder and stronger, cheer louder and longer, live freer and hold our liberty dearer, than we ever have before. We will do this because it's who we are. We will do this because we're Americans.
Sunday, I will join more than 20,000 athletes in that most rare of occurrences, a sporting event that transcends sports. Buoyed by our own emotions and the support from all of you, we will run like the wind, striving with every step to show the world the indomitable spirit of America.
Am I still going to run? Heck no. I am going to fly.
