NEXT month Mike King will swap his business attire for joggers when he laces up for Relay For Life.
Mr King will run for 18 consecutive hours, stopping only for food and water.
Motivated by his personal experiences, the Kotara long-distance runner will take part in the Newcastle/Lake Macquarie Relay For Life for the first time.
His sister and brother-in-law have both battled cancer, both when aged in their 40s.
On top of this, Mr King has sadly watched a few friends succumb to the disease.
"You hear about it [cancer], but you don't expect it to be that close to home," Mr King said.
"But running in Relay For Life is a good cause, irrespective of personal experience."
Mr King started running regularly just three years ago, starting with friends a few mornings a week.
He has come to love it, participating in events such as the 100-kilometre Oxfam Trailwalker.
With a goal of running 125 kilometres in 18 hours, Mr King is confident he can outdo his 2011 personal best, describing Relay For Life as "literally a walk in the park".
So far, Mr King has raised $375 towards his $500 fund-raising goal.
■ The Newcastle/Lake Macquarie Relay For Life will be held on November 2 at the Hunter Sports Centre, Glendale and is sponsored by The Star.
