Boston Marathon icon Rick Hoyt passes away at 61.

Rick Hoyt, who with his father pushing his wheelchair became a fixture at the Boston Marathon and other races for decades, has died at the age of 61 due to complications with his respiratory system. Hoyt had cerebral palsy, which left him a quadriplegic, but he and his father became as much a part of the Boston Marathon as sore feet or Heartbreak Hill. The father and son pair also participated in more than 1,000 other races, including duathlons and triathlons.
