'Deliberately absurd' is how a Christchurch mountain biker describes his idea to cycle around a McDonald's drive-thru for 24 hours. 

21-year-old Matthew Fairbrother clocked up 500 kilometres on the ride on Christmas Day. 

Fairbrother told Andrew Dickens it may be a world record of some sort, as he's not aware of anyone doing something similar. 

He concedes the idea was a bit pointless, but was to put himself to the test and see what he could achieve when his mind was put to something.
