The 250-strong Tranz Alpine Scooter Safari, which will make its way to Hokitika this weekend after a slow crawl from Christchurch, had raised $137,324 by this morning.
Starting at dawn on Saturday, 250 people mounted on 50cc scooters will leave Christchurch and ride 252km across the alps to arrive in Hokitika around sunset. All proceeds will go to the New Zealand Cancer Society
The event is described as "the coldest, longest, hardest, most gruelling and uncomfortable test of endurance on a city scooter".
"We have been totally blown away by the interest in the event and amount of funds raised for the Cancer Society," organisers Jayne and Mike Rattray, of Christchurch, said today.
"We never even imagined that when we came up with this crazy idea in 2009 that it would snowball into the huge event that it is today."
