Iconic Boston Marathon runner Dick Hoyt has died at 80

Iconic Boston Marathon runner Dick Hoyt died Wednesday at the age of 80. Hoyt, a fixture in the race for decades, died in his sleep after dealing with a series of health issues, his family said.

Hoyt first ran the Boston Marathon in 1980 while pushing his son, Rick, in a wheelchair. Rich was born a spastic quadriplegic with cerebral palsy, CBS Boston reports.  The two began racing in marathons across the country in 1977. Hoyt retired from the Boston Marathon in 2014 but his son continued to participate with the help of Bryan Lyons, who replaced Hoyt in 2015.
