Barriers only exist because we create them for ourselves.
If you haven't heard about the inspiring, near-impossible achievements of Ironman competitors Brent and Kyle Pease, their website will bring you up to speed.
And as amazing as they are athletically, what they've created for young, aspiring athletes with disabilities will knock your socks off.
These are the stories of two of these sponsored athletes, Hank Poore and Emanuel McFarland. Next month, we'll share their experiences at the New York City Marathon.
Please give these a watch. I promise they'll leave you smiling.
