In a twist of fate, the two families crossed paths for the first time 19 years before.
Lewis' son was born at the same hospital as David Moore, within days of each other.
"I could have been standing shoulder to shoulder with Spencer looking into the nursery window without knowing it... and as my son pointed out, just think about it - you could have been looking through that window, at a baby who would save your life 19 years later," said Lewis.
Lewis and Moore's father have a message for everyone. Sign up to be a donor. It can change a life.
"Put the heart on the card. In other words, let people know you want to be a donor and tell your family. Let them know you want to be a donor. That's very important," said Spencer Moore, Officer David Moore's father.
"It means I'm still alive... it means that David's gift is still working for me and others... it's just a real blessing to be able to compete," said Lewis.
Transplant donor families and recipients are invited to sign the Transplant Games of America flag on Sunday, February 28, from 1 - 5 p.m., at 2nd Presbyterian Church of Indianapolis.
The flag is traveling to all 50 states to gather signatures and it will fly at the games in Cleveland.
We'll be sure to update you on Lance's race in the games.
He sums it all up this way, "After receiving a transplant and receiving the gift of life, you realize how precious life is... so you focus on things that are family and and friends and the stuff that's important.. and the other stuff you just brush aside. It just gets in the way."
