Taupo x 3 Relay
The men's relay team finished in 33 hours 31 minutes 15 seconds and included Steve Junk (Australia), Mark Cockroft (New Zealand), Dougal Hunt (Australia), Chris Palfrey (Australia), and Stephen Spence (Australia) with New Zealand legend Philip Rush as the escort pilot. The women’s relay team finished in 33 hours 33 minutes 45 seconds and included Julie Bradshaw (England), Michelle Macy (USA), Barbara Pellick (Australia), Penny Palfrey (Australia), Lucy Roper (England), and Heather Osborn (New Zealand).
The plan was to start at first light from near Tokaanu, at the southern most point of the lake, heading roughly north east past Motutaiko Island, cutting close to Rangitiri point, before finishing on the beach in front of the Waikato River. The distance by GPS for one lap was 40.2 km. The second lap retraced the course back to the starting point and the final lap was a repeat of the first.
The men finished the first leg of 40.2 km in a time of 10 hours 22 minutes; the women finished in 10 hours 28 minutes. The men finished the second leg of 40.2 km in 12 hours 15 minutes; the women finished in 12 hours 19 minutes. The men finished the third leg of 40.2 km in 10 hours 54 minutes; the women finished in 10 hours 53 minutes. Both teams broke the world relay record set in December 2008 by 2 teams of 50 swimmers, each doing 2 km, who covered 100 km in 37 hours 6 minutes.
