Dick and Rick Hoyt
Team Hoyt-a father and his physically disabled son who compete in a huge variety of races including the ultimate-Ironman. Dad Dick swims pulling his son Rick in an inflatable boat behind him, then cycles with him on a specially adapted chair bike, then runs pushing Rick's chair in front on him. And they still complete the Ironman in under the cut off time. Inspiration is not the word!
Team Hoyt: Dick Hoyt has completed over 1000 races with his son Rick Hoyt who is paralyzed, including an Ironman Triathlon in which he pulled him 2.4 miles in a boat while swimming, rode 112 miles with him the front of his bicycle, and then 26.2 miles of pushing him in his wheelchair while he ran. The ultimate example that NOTHING is impossible.
