Event founder Jeremy Burfoot said the 13 riders hit rough waters yesterday at Cape Saunders, where they encountered waves of up to 5m.
''That was exciting,'' he said.
The group aims to raise almost $100,000 for Melanoma New Zealand.
Day one of the challenge was supposed to be Invercargill to Stewart Island, but that was abandoned due to Sunday's ''foul weather''.
The group substituted that leg with a day on the Clutha River, before completing Invercargill to Balclutha on Monday.
Another four riders would join the group for the North Island leg.
The journey ends in Auckland on March 18.
