Marathon man Tommy Joyce is setting his sights on yet another record breaking attempt.
Tommy Joyce was named Yorkshireman of the Year in August
Earlier this year, Mr Joyce, of Mexborough, South Yorkshire, ran a lung-busting 527 miles and 700 yards by completing 20 marathons in 20 days.
His effort raised around £10,000 for cancer charities but on Thursday he is starting his attempt to break the world-record for running on a treadmill which currently stands at 150.2 miles in 48 hours.
Mr Joyce will be cheered on by friends, supporters and shoppers in the front entrance to the Tesco supermarket in Balby.
This time he is raising money for both the Bluebell Wood Hospice Appeal and the Mexborough Christmas lights fund.
In August, the former professional boxer was named Yorkshireman of the Year in the Heart of Yorkshire Awards staged by the BBC and the Variety Club of Great Britain.
Before starting his run Mr Joyce told BBC Look North: "I will have to take a break and get a couple of hours sleep.
"But I want to notch up a few miles first and see what happens and how my body feels.
"It's going to be great."
