His is an amazing story of love.

Dick Hoyt, the man who famously pushed his son Rick in a custom racing wheelchair through 32 Boston Marathons and more than 1,000 total races, died yesterday at 80.

Hoyt died peacefully in his sleep in Massachusetts, one of his three sons, Russ Hoyt, told the Associated Press. 

If you don’t know who he is, please watch this. Inspiring.
