"It came down the west coast and then jumped across to the east and smashed this side.
"So these things don't run on rails."
The modified course, a triple climb up the 399m-high peak, meant a 41km journey - in wet, windy and humid conditions - for individual and team runners, and a 39km trail for bikers.
It made the event easier to manage if the weather had become a safety concern, Mr Tait said.
"If we had needed to call the race short we could still have had a winner and could have kept people safe by calling them in as they were coming in and out of the transition [area] in the domain.
"If it had been the full course they would have been stretched out across the three peaks."
An upside of the change was that it created a "nice environment" in the transition area that hadn't been seen in previous events, with onlookers cheering competitors on as they arrived and departed.
"We were pretty happy we could still deliver an event for people and they haven't missed a year," Mr Tait said.
