Ultra Marathon Cyclist Arvid Loewen is back at it.

Starting today, the 57 year old grandfather of nine, will embark on a grueling journey to beat the Guinness World Record for the fastest cycle to 10,000 kilometres.

He talks a bit about why he is doing this.

In order to accomplish this task, Loewen will need to cycle around 450 kilometres per day which will take between 18 and 20 hours to complete, with only 3 hours left to sleep.

Loewen explains why he continues to take on such tasks...

The current record is held by Gus Moonen from the Netherlands, who completed the distance in 22 days, 15 hours and 34 minutes.

Loewen's record beating journey will get underway this morning at 10am at 5839 Henderson Highway, just north of Winnipeg.
