Sounds like a challenging race (no pun intended) and already a friend of mine here in NZ wants to do it while her sister is still living in the UK.
The old kiwi mentioned earlier is a legend here, called Garth Barfoot. He's done IMNZ, Challenge Wanaka, Challenge Copenhagen and Coast to Coast.
I think he did C2C and IMNZ the same year (they are 3 weeks apart).
I've looked on the results and he has a finish time of 15:51 but it says he was withdrawn during the race. How does that work?
Feijoas do not taste of deep heat. They won't be in season anyway, fruit still ripening although I saw some in the supermarket today for almost $10 a kg!
Anzac biscuits a definite however.
