Officials have cancelled a 2020 Horsham triathlon, citing river depth and health as the motivating factor.
Tri Horsham director Mark Pumpa said organisers had decided to cancel the February 8 event after careful consideration.
"We are concerned about the depth of the river at Sawyer Park and the general health of the water," he said.
"We have a duty of care to our competitors and we just couldn't guarantee the river would be right."
