THE results of the Dusi Canoe Marathon will be amended after canoeist Wayne Volek, who finished third in the race, was found guilty on Thursday evening of doping in the event. Canoeing South Africa’s executive committee suspended him from competition for two years, as stipulated by the International Canoe Federation rules on doping. Volek was also disqualified from the marathon and had to return the prize money and medal he won in the race.
