Triathlete Hayden Wilde is attempting to break one of the longest standing records in New Zealand's athletics history.
This Saturday at Mt Smart Stadium in Auckland Wilde will try to better the national one hour record of 20 thousand, 190 metres set by the late great Bill Baillie in 1963.
Only Sir Peter Snell's 1962 800 metre record has stood for longer in Athletics New Zealand's record books.
Wilde has spoken to sports reporter Brenton Vannisselroy about why he's having a crack at the hour record.
