Fundraisers from the Steve Prescott Foundation have completed the challenge of running four marathons in four days.
Runners set off on Monday from Hull and arrived at Old Trafford 24 hours before the Super League Grand Final.
"This was my hardest challenge so far," said former St Helens and Hull full-back Prescott, who was diagnosed with a rare form of stomach cancer in 2006.
"I'm relieved that I got through it. Now I'm going to recharge my batteries, then it's on to my next challenge."
The Steve Prescott Foundation raises money for The Christie Hospital in Manchester and Try Assist, the rugby league benevolent fund which supports injured former rugby league players.
