A Tasmanian man has been training since last Christmas to break the Guinness Book of Records world static cycling record.
Eddy Kontelj started the fete July 23 and has already broken the current record of 111 hours, 11 minutes and 11 seconds. He is expected to continue the stationary cycling through at least Monday, getting a record high enough to ward off any potential breakers.
"It feels fantastic -- we put a lot of hard work into preparing for the event and to finally get there is a great feeling," Kontelj said.
Kontelj has suffered from blisters, fatigue and aching limbs, but has a doctor and support team on hand to monitor his condition and encourage his efforts.
Under the terms of the Guinness Book of Records, he had to maintain an average speed of 20km/h and was allowed one five-minute break every hour which he accrued for less than three hours sleep.
Kontelj is using the record breaking attempt as a charity fundraiser to heighten awareness of depression and raise money for Beyond Blue.
