He is the only German sportsman to have won Olympic medals in both walking disciplines at the Games.
He was unable to participate in the 1984 Summer Olympic Games because of the East German boycott, when overwhelming favourite to win.

After the games, Weigel went back to Germany and took over from his previous trainer, Hans-Joachim Pathus as the German national trainer. His admitted work for the East German security service was taken into consideration, but was not deemed to be a hindrance in hiring him.
