Dangerously high levels of bacteria from sewage flowing into the Umsunduzi River could see Pietermaritzburg lose the Hansa Powerade Dusi Marathon. Yesterday, the Natal Canoe Club put up signs at Camps Drift warning paddlers to steer clear of the Umsunduzi. “Tomorrow we will redesign the start so we can move it at a moment’s notice. We can’t afford not to have a plan B and have everyone seriously ill. If this step is taken, it will be a major blow to the event and sports tourism in this province,” De Vries said.
