He was cited by major Canadian media as Canada's best gold medal hope for the 1912 Olympics. During training for the Olympics, he ran into conflicts with chief coach Walter Knox; according to the "Manitoba Free Press" of June 27, 1912, Knox accused Howard of insubordination, and, in an era when discrimination against black athletes was common, threatened to expel him from the team. The efforts of the Amateur Athletic Union of Canada kept Howard on the team. In the Olympics in Stockholm, he was hindered by a stomach ailment and stress resulting from discord with coach Knox, and was eliminated in the semi-finals of the 100 metres competition as well as of the 200 metres event. He was also a member of the Canadian relay teams which were eliminated in the semi-final of the 4x100 metre relay competition and in the first round of the 4x400 metre relay event.
