One day, a son asks his dad, "Dad, would you like to run a marathon with me? "

The father says, "Yes".

And they ran their first marathon together.

Another time, the son asks his dad again, "Dad, would you like torun a marathon with me?"

The father says, "Yes, son".. And they do.

One day, the... son asks his father, "Dad, would you run the Ironman with me?"

The Ironman is the most difficult triathlon ever: 4 km swimming, 180km biking, 42 km running?

His father says, "Yes".

The story looks simple until you watch this Video:This is something else, fair play to the father!

Pretty amazing stuff. I believe its the same father/son duo that I used to watch fly by me 20 years ago at the Boston Marathon.

Truly amazing and heartwarming.

Note: Yup, it's the same duo...I can tell by the thick Boston accents

The love some fathers will show for their sons. It amazes me to no end.

yes, it amazed me to.. the greatest love of all... Thank you for sharing..
